ASN Sponsoring Guide: How to Get Your Own ASN & IP Addresses in 2026

Getting your own ASN can give your business greater control over internet connectivity, routing and IP addresses. However, the registration process can feel confusing if you are new to network management. ASN sponsoring offers a simpler way to obtain an Autonomous System Number without managing a full registry membership yourself.

Through a Sponsoring LIR, you can complete the registration process and access the resources needed to build your network. Whether you operate a hosting company, ISP or data center, understanding BGP routing, IPv4 address leasing and RIPE NCC requirements will help you make better decisions. This guide explains everything you need to know in 2026.

1. Understanding ASN Sponsoring & IP Addresses: Do You Really Need Your Own?

An Autonomous System Number (ASN) gives your network a unique identity on the internet. It helps other networks recognize your routing information and understand which IP addresses you manage. Networks exchange this information through Border Gateway Protocol (BGP). Without an ASN, you generally depend on another provider’s network identity and routing arrangements.

ASN sponsorship offers another way to obtain registry resources. Instead of managing direct registry membership, you work with an existing member that handles the application and related administration. This arrangement can reduce paperwork and simplify resource management. However, you must still arrange suitable IP addresses, routing authorization and an upstream connection.

What Is an Autonomous System Number (ASN)?

An ASN is a unique number assigned to an autonomous system. An autonomous system is a group of networks managed under one routing policy. Internet service providers, hosting companies and large enterprises use ASNs to exchange routing information with other networks. Each network can then identify the source of a route and make decisions about traffic.

ASNs support Autonomous System routing across the global internet. They come in two main formats: two-byte and four-byte numbers. Four-byte ASNs support a much larger number of networks. RFC 6793  explains the four-byte ASN format and its use in modern routing systems.

For example, imagine that your hosting company operates servers in New York and Chicago. You connect both locations to different internet providers. Your ASN helps identify your network when those providers exchange routing information. You can then manage your own routing decisions instead of depending entirely on one provider’s network identity.

What Is ASN Sponsorship and How Does It Work?

ASN sponsorship allows an organization to obtain an ASN through an existing internet registry member. In the RIPE region, this member is called a Sponsoring LIR. The sponsor submits the request and handles the required registration work. It may also help maintain your registry records and manage renewal-related tasks.

Your agreement explains the responsibilities of both parties. It should cover service charges, contact updates, resource use and termination conditions. Under RIPE policies, sponsored resources are registered to the receiving organization. The sponsor does not automatically become their owner. You should also understand how resource transfers work before signing an agreement.

When Does Your Business Need Its Own ASN and IP Addresses?

Your business may need an ASN when it wants independent control over internet routing. This is especially useful for hosting providers, cloud platforms, regional ISPs and data centers. These businesses often connect to multiple upstream providers. If one connection fails, another can continue carrying traffic. This arrangement improves network redundancy and reduces dependence on a single carrier.

An ASN can also help you change internet providers without changing your network identity. You may use portable IP prefixes and establish direct peering relationships. However, a small website or ordinary VPS rarely needs its own ASN. The hosting provider already manages the routing infrastructure. In that situation, paying for independent resources may add cost without providing much value.

Public ASN vs Private ASN: Which One Should You Choose?

A public ASN identifies your network in global internet routing. Other networks can recognize it when you announce authorized IP prefixes through BGP. A private ASN serves a different purpose. It is mainly used inside private networks, laboratories and controlled routing environments. Private ASNs are not normally advertised as independent identities on the public internet.

The right choice depends on your network requirements. If you need independent routing with multiple internet providers, a public ASN is usually more suitable. If you only need internal routing between private systems, a private ASN may be enough. You should also consider future growth before selecting an addressing and routing design.

ASN type	Main purpose	Typical use
Public ASN	Global internet routing	ISPs, hosting companies and data centers
Private ASN	Internal or private routing	Enterprise networks and laboratories

Benefits of Owning Your Own ASN

Owning an ASN gives you more control over how traffic enters and leaves your network. You can work with different transit providers and adjust routing preferences. This flexibility becomes valuable when your business expands into new locations. It also helps you avoid depending on one provider for every routing decision.

Another benefit is IP address portability when you hold suitable portable resources. You can move between compatible upstream providers without changing your network identity. Your business can also establish direct peering relationships and use custom routing policies. For companies that depend on reliable connectivity, these advantages can support long-term network growth.

Can You Get an ASN Without Multiple Internet Providers?

The answer depends on the internet registry handling your request. Under the current RIPE-679 policy, a network must be multihomed to qualify for an ASN. This generally means using two upstream providers or one upstream provider alongside a qualifying peering relationship. You should confirm that your planned network meets the current requirements before applying.

ARIN follows its own policies for ASN assignments. Its rules do not simply copy RIPE’s multihoming requirement. ARIN’s standard policy allows an organization to request one ASN, while additional ASN requests need suitable technical justification. Therefore, US businesses should review ARIN’s current requirements instead of assuming that every registry follows the same process. See the ARIN ASN request guidance .

2. How to Get Sponsored ASN & IP Addresses Through RIPE NCC

Before applying, identify which regional internet registry serves your organization and network. American businesses generally deal with ARIN, while RIPE NCC serves Europe, the Middle East and parts of Central Asia. A RIPE NCC member can provide sponsorship for eligible resources in its service region. However, a US company should not choose RIPE sponsorship simply because a provider offers it.

The ASN application process depends on the registry, resource type and business requirements. You may apply directly or use an existing member when sponsorship is available. Both options require accurate organization information and a clear technical reason for requesting resources. Understanding these differences early can prevent unnecessary delays and unexpected costs.

ARIN vs RIPE NCC: Which Internet Registry Should US Businesses Choose?

For a US-based organization, ARIN is generally the first registry to investigate. ARIN manages internet number resources for the United States, Canada and parts of the Caribbean and North Atlantic region. It allows eligible organizations to request ASNs directly. You need an ARIN Online account connected to an authorized organization and contact record.

RIPE NCC manages a different geographical region. Its registration process includes direct membership and sponsored resource arrangements. A US business may have international operations, but that alone does not automatically make it eligible for RIPE resources. You should review regional eligibility and the actual network requirements before selecting a sponsoring provider.

Feature	ARIN	RIPE NCC
Main service region	United States, Canada and parts of the Caribbean	Europe, Middle East and parts of Central Asia
ASN registration	Direct application	Membership or sponsored assignment
Membership	Not required for every ASN request	Required for direct member resources
Sponsorship	Not the standard route for ordinary ASN requests	Available through a sponsoring LIR
Main policy reference	ARIN NRPM	RIPE policies

Who Can Sponsor an ASN Through a RIPE NCC LIR?

An existing RIPE NCC member can act as a sponsoring LIR when it meets the relevant requirements. The sponsor works with you to prepare the request and submit the required information. It also maintains the contractual relationship needed for the sponsored resources. This can make registration easier for businesses that do not want direct membership.

The sponsor should explain its responsibilities before you sign anything. Ask how it handles contact updates, database changes, technical questions and annual charges. Also check what happens if you stop using its services. A reliable Sponsored ASN provider should explain the process clearly and avoid hiding important conditions in complicated contract language.

Direct ASN Registration vs Sponsored ASN: Which Is Better?

Direct registration gives your organization a direct relationship with the relevant registry. In the RIPE region, this usually means Direct RIPE membership through an LIR account. You manage your own registry responsibilities and pay the applicable membership charges. This approach may suit established ISPs and hosting companies that need several resources.

Sponsored registration is often more practical for smaller businesses. You avoid creating and maintaining your own LIR account. Instead, the sponsoring provider handles the registry relationship for the sponsored resources. However, you still need to understand the agreement and maintain accurate information. The best option depends on your network size, budget and administrative capacity.

Factor	Direct membership	Sponsored ASN
Registry relationship	Direct	Through a sponsor
Administrative work	Managed by your organization	Shared with the sponsor
Initial expense	Membership and applicable fees	Sponsor setup charges
Ongoing expense	Annual registry charges	Sponsor renewal charges
Suitable for	Larger network operators	Smaller networks and businesses

Requirements and Documents Needed for ASN Sponsorship

A sponsoring provider needs enough information to confirm your identity and understand your network. The exact ASN registration documents depend on the registry and your legal status. A company may need a recent business registration extract. An individual may need identity verification. You should also prepare technical contact details and information about your upstream providers.

The sponsor uses these details to prepare the ASN assignment agreement and registry records. Under the RIPE framework, RIPE-637 explains the contractual requirements for sponsored resources. The sponsor may also create your organization record and technical contacts in the RIPE Database. Accurate information matters because incorrect records can cause problems during future updates or routing checks.

Document or detail	Purpose	Usually prepared by
Company registration extract	Confirms legal identity	Applicant
Identity document	Verifies an individual	Applicant
Sponsorship agreement	Defines contractual responsibilities	Sponsor and applicant
Technical contacts	Identifies network administrators	Both parties
Abuse contact	Provides a reporting address	Applicant
Upstream information	Supports routing policy preparation	Applicant

The RIPE NCC registration requirements can change according to the resource type and current policy. Therefore, ask your sponsor to confirm the latest document list before submitting anything.

Step-by-Step Process to Get Your Own Sponsored ASN

The first step is choosing the correct registry and checking your eligibility. Once you understand the regional rules, contact a suitable sponsoring LIR. Explain your business model, network locations and routing plans. The sponsor can then tell you whether your request fits its services and the applicable registry policies.

Next, prepare your documents and agree on the contract terms. The sponsor submits the request through the relevant registry process. It may ask follow-up questions about your routing policy or upstream connections. After approval, your ASN appears in the registry records. You can then prepare your IP prefixes, routing authorization and BGP connections.

The ASN allocation process is not complete from an operational point of view just because you receive a number. Your network still needs valid routing records and an upstream willing to accept your announcements. Plan these technical steps before applying. Doing so can help you move from registration to a working network more smoothly.

How to Obtain Your Own IPv4 and IPv6 Addresses

An ASN and an IP address block are separate resources. Receiving an ASN does not automatically give you IPv4 or IPv6 addresses. You must obtain suitable address space through your regional registry, an address holder or an authorized leasing arrangement. Your choice depends on the registry, your location and the intended use of the addresses.

Provider Independent (PI) addresses can support network portability because they are not tied to one particular internet provider. However, they come with specific registry rules and usage conditions. Provider Aggregatable addresses usually come from an upstream provider and may need to change when you switch networks. Understand these differences before making a long-term plan.

How Long Does ASN Sponsorship and Registration Take?

There is no single processing time for every application. A straightforward request may move quickly when documents and technical details are ready. However, registry questions, identity checks and incomplete information can extend the process. Your sponsor should give you a realistic estimate based on current processing conditions.

Direct membership may take longer because your organization must complete the membership process and related agreements. You should also allow time for database records, address authorization and upstream coordination. Do not schedule a network launch around an estimated approval date alone. Keep enough time for testing and troubleshooting.

Common Mistakes to Avoid During ASN Registration

One common mistake is choosing a registry without checking its service region. Another is assuming that ASN registration automatically includes IP addresses. Businesses also overlook contract conditions, renewal charges and routing requirements. These mistakes can create delays or unexpected expenses after the application begins.

A better approach is to prepare your technical plan before contacting a sponsor. Confirm your upstream providers, address requirements and routing policy. Review the agreement carefully and ask who controls each registry record. Clear answers at the beginning can prevent difficult conversations later.

3. ASN Sponsoring Costs, IP Address Configuration & BGP Routing in 2026

Getting your ASN is only one part of building an independent network. You must also budget for IP addresses, internet transit, routers and technical support. The total ASN registration cost depends on your registry and the services you need. A sponsored arrangement may cost less initially, while direct membership gives you more administrative control.

Your technical setup matters just as much as your budget. You need properly registered prefixes, valid routing records and an upstream connection. You must also configure BGP, test route announcements and monitor network traffic. This section explains the main expenses and technical steps involved in launching your own network.

How Much Does ASN Sponsorship Cost in 2026?

ASN sponsorship prices vary between providers. A sponsor may charge a setup fee, an annual service fee or both. The RIPE NCC charging scheme also affects the underlying cost of sponsored resources. For 2026, RIPE NCC charges €50 per ASN assignment and €75 per independent resource assignment under its published scheme.

Direct membership has a different cost structure. The 2026 RIPE NCC annual fee is €1,800 per LIR account. New members also pay a one-time €1,000 sign-up fee. These charges are separate from equipment, transit and address market costs. You should also check the applicable LIR account fees and ASN yearly maintenance fee before choosing a registration route.

For 2027, RIPE NCC has published a higher annual LIR fee of €1,894. Its charging scheme includes the first ASN registered to an LIR account in the annual fee. Additional ASNs cost €50 each. Independent resource assignments remain subject to the applicable €75 charge.

ARIN vs RIPE NCC: ASN Registration and Membership Cost Comparison

US businesses should pay close attention to ARIN’s fee structure. ARIN uses service categories based on the resources held by an organization. Its 2026 fee schedule lists $275 annually for the 3X-Small category. This category covers organizations with one to three ASNs and qualifying smaller address holdings. The fee is not simply a standalone price for one ASN.

RIPE NCC uses a different model. Its charges depend on membership, sponsored resources and applicable independent assignments. A sponsored ASN provider may add its own service charges. Therefore, comparing only the registry’s ASN fee will not show the complete price you pay.

Cost factor	ARIN	RIPE NCC
Basic registration	Based on applicable request and policy	Membership or sponsorship
2026 annual fee	Starts at $275 for 3X-Small	€1,800 per LIR account
New member fee	Depends on ARIN registration arrangements	€1,000 sign-up fee
ASN charges	Included in applicable service category	€50 per ASN assignment
Independent resource charge	Depends on applicable ARIN fees	€75 per assignment

These figures describe registry charges, not complete network costs. Always check the current ARIN fee schedule  and RIPE NCC charging scheme  before preparing your budget.

IPv4 Address Costs: Buying vs Leasing vs Registry Allocation

IPv4 addresses remain valuable because the available supply is limited. Many businesses need an IPv4 /24 prefix because it contains 256 addresses and is commonly accepted for global routing. However, registry allocation is not always available. Organizations often consider the IPv4 address market when they need portable address space.

There are three common options. You can join an available registry waiting list, purchase address space through a transfer or lease it from an address holder. IPv4 address purchasing can provide long-term control, but it requires a larger upfront investment. IPv4 address leasing usually costs less initially, although the contract may limit your rights and flexibility.

Option	Main advantage	Main concern
Registry allocation	Official allocation through the registry	Limited availability
Address purchase	Long-term control	High upfront cost
Address lease	Lower initial expense	Ongoing payments and contract risk

IPv6 Address Allocation: What Does a /48 or /32 Mean?

IPv6 provides a much larger address space than IPv4. A IPv6 /48 prefix is a common size for an independent network assignment. It gives you enough addresses to organize many internal networks and services. A IPv6 /32 allocation is larger and may be suitable for an LIR that needs to assign address space to customers.

The exact allocation depends on the registry and the type of resource. A sponsored PI assignment may have different usage conditions from an allocation made to an LIR. For example, a PI block may be intended for the holder’s own infrastructure rather than customer assignments. Check the applicable IPv6 address allocation policy before using the space.

Good IPv6 planning also makes future network growth easier. You can divide a larger prefix into smaller subnets for data centers, offices and customer services. This keeps addressing organized and reduces the need for major changes later. Your upstream provider must also support IPv6 routing before you can announce the prefix globally.

How to Verify Leased IP Addresses Before Using Them

Leasing an IP block without checking its history can create serious problems. A prefix may have been used for spam, scanning or other abusive activity. This can damage its IP address reputation and affect email delivery. Before signing a lease, review public reputation databases and investigate the prefix’s previous routing activity.

Check the IPv4 route history through tools such as RIPEstat. Review the block on Spamhaus and other relevant reputation services. Ask the address holder for a Letter of Authorization (LOA) that identifies the prefix and your ASN. You should also confirm who manages the route object and ROA. These checks help establish proper IP prefix authorization before announcing the addresses.

Your lease agreement should explain who handles abuse reports and what happens if the block becomes unusable. Ask whether the lessor will replace addresses that develop serious reputation problems. Also confirm the monthly IPv4 lease pricing, payment terms and cancellation conditions. A low price is not useful if the addresses cannot reach your customers reliably.

How to Configure IRR and RPKI for Your ASN

Before announcing your prefixes, you need correct routing information in public databases. The Internet Routing Registry (IRR) stores routing policy information that networks use to build filters. You may need an AUT-NUM object to describe your routing policy. You also need the relevant Route object for IPv4 or Route6 object for IPv6.

These records use RPSL routing policy syntax. You can describe which upstream providers you use and which prefixes your network announces. An AS-SET groups your autonomous system information for upstream networks. Your provider can use this information when building routing filters. Incorrect records may cause your announcements to be rejected.

Resource Public Key Infrastructure (RPKI) adds another layer of routing security. A Route Origin Authorization (ROA) identifies which ASN is allowed to announce a particular prefix. The process supports prefix origin validation and helps networks detect unauthorized announcements.

RIPE Network Coordination Centre

There are three common validation results. A valid route matches an authorized ROA. An invalid route conflicts with the authorization information. A not-found route has no matching ROA. An RPKI invalid route can be rejected by networks that enforce origin validation. This is why you must check your records before announcing a prefix.

An ASPA object can provide additional information about your authorized upstream providers. It is designed to support stronger path validation. However, you must keep the information accurate as your network changes. Good BGP route security depends on correct records and regular maintenance rather than creating objects once and forgetting them.

How to Establish Your First BGP Session

Your first BGP session connects your network to an upstream provider. The provider gives you its ASN, neighbor IP addresses and routing requirements. You provide your ASN and the prefixes you are authorized to announce. Both sides then configure the connection and agree on which routes they will exchange.

A typical BGP session configuration includes the local ASN, remote ASN and neighbor addresses. You also need suitable import and export filters. These filters control which routes your router accepts and announces. Your BGP routing policy should allow only the prefixes you intend to advertise. This helps prevent accidental route leaks.

Your upstream may provide a BGP default route or a BGP full routing table. A default route is simpler and requires fewer router resources. A full table gives your network more routing choices but needs more memory and processing power. The right option depends on your network size and traffic requirements.

Basic BIRD Configuration for Your First BGP Session

The BIRD routing daemon is a popular option for running BGP on Linux servers. It allows network operators to configure neighbors, routing tables and filtering rules. A basic BIRD BGP configuration can establish a session with one upstream provider. You should test the setup in a lab before using it on a production network.

For example, a lab may use documentation IP addresses and private ASNs to test routing behavior. You can define your local ASN, remote neighbor and authorized prefixes. Then apply strict export filters so the router announces only your own address space. This is important because an incorrect export policy can leak routes to other networks.

Other routing platforms are available too. FRRouting provides routing services on Linux systems. MikroTik RouterOS 7 supports BGP for many small and medium networks. VyOS BGP configuration is another option for software-based routers. Your choice should depend on hardware, technical experience and the features your network needs.

BGP Routing Equipment and Infrastructure Requirements

Your router must have enough resources for the routes it receives. A default-route setup can run on relatively modest hardware. A full routing table needs more memory and processing power. If you connect to several upstream providers, resource use can increase quickly. Always check current routing table sizes and vendor recommendations before choosing equipment.

You should also consider network interfaces, redundancy and monitoring. A router with enough memory may still struggle if its CPU or interface capacity is unsuitable. Production networks often use redundant devices and separate power sources. These measures help reduce downtime when hardware or connectivity fails.

How to Choose a Reliable IP Transit and BGP Upstream Provider

Your upstream provider plays a major role in network performance. Look at its network coverage, peering relationships and available transit locations. Ask whether it supports IPv4 and IPv6 and whether it accepts your leased prefixes. You should also review its technical support and service-level agreement.

A good IP transit provider should explain its routing policies clearly. Ask about BGP communities, prefix limits and route filtering. Find out how it handles outages and DDoS attacks. You should also check whether it offers a default route, full tables or both. These details help you choose an upstream that fits your network.

For US businesses, geographic coverage matters. A provider with strong connections in New York may not offer the same performance in Los Angeles or Dallas. Compare latency, capacity and available points of presence. The cheapest transit option is not always the best choice for a business that depends on stable connectivity.

4. Launching Your Own ASN: Practical Checklist, Common Questions & Next Steps

Receiving an ASN is an important step, but your network is not ready until it can exchange traffic. You must verify your address records, configure your routers and establish working upstream connections. You should also test your announcements before allowing production traffic. A careful launch reduces mistakes and makes troubleshooting easier.

The final stage involves ongoing maintenance. You need to monitor routing changes, renew sponsorship agreements and keep contact information accurate. This ASN Sponsoring Guide would not be complete without explaining how to maintain your network after launch. The following steps cover practical checks, common problems and questions that businesses often ask.

Complete ASN Sponsoring and IP Address Registration Checklist

Before launching your network, review every important registration and technical requirement. Your organization should have a valid ASN and authorized IP prefixes. Your routing records must match the announcements you plan to make. You should also confirm that your upstream provider has accepted the required information.

A useful checklist should cover registration, address authorization and connectivity. It should include your RIPE Database records, ROAs and upstream configuration. For US organizations, also check that your ARIN records are accurate. Keep copies of your agreements and technical information so your team can review them when needed.

How to Announce Your First IP Prefixes on the Internet

Your first BGP route announcement tells other networks that your ASN can reach a particular IP prefix. Before announcing anything, confirm that you control the address space or have permission from its holder. Check that your route records and ROAs identify the correct origin ASN. Your upstream provider must also accept the prefix.

After configuration, check whether the route appears in public routing tools and looking glasses. Confirm that the prefix has the correct origin ASN. Review BGP route propagation to see whether other networks can learn the route. If the announcement does not appear, investigate filters, authorization records and upstream policies before changing your configuration.

How to Monitor and Maintain Your Own ASN

Network management does not stop after your first successful announcement. You should monitor BGP sessions, route changes and upstream connectivity. Your monitoring system should alert you when a session drops or a prefix disappears. This helps your team respond before customers experience a serious service interruption.

Keep your registration details and Network abuse contacts current. Review ROAs whenever you change providers or address allocations. You should also check your sponsor agreement and renewal dates. Regular maintenance helps protect your routing setup and reduces the risk of unexpected service problems.

Common ASN Sponsoring Problems and Their Solutions

Even a well-planned network can experience problems. An application may be delayed because documents are incomplete. A route may disappear because its ROA identifies the wrong origin ASN. A BGP session may fail because the neighbor addresses or authentication details do not match. Each problem needs a different investigation.

The best approach is to check one layer at a time. Start with the registry records, then review routing authorization and upstream configuration. Check logs and session status before changing production settings. Avoid making several changes at once because this can make the original problem harder to identify.

Common problem	Possible reason	What to check
ASN application delay	Missing documents	Organization and contact information
Prefix rejected	Incorrect authorization	LOA, route object and ROA
BGP session fails	Neighbor mismatch	ASN, IP address and connection settings
Route not visible	Upstream filtering	Prefix limits and export policy
RPKI invalid status	Incorrect ROA	Origin ASN and maximum prefix length
Traffic interruption	Upstream failure	Alternative routes and BGP failover

For additional routing protection, consider using RFC 8212 as a reference for safe external BGP filtering. It describes default behavior that helps prevent unintended route propagation. Your network should have clear import and export policies before connecting to production upstreams.

Case Study: How a Small Hosting Company Can Benefit from Its Own ASN

Imagine a small hosting company operating servers in New York. Initially, it uses one internet provider and receives IP addresses from that provider. This setup works well until the company wants to change carriers or add another data center. Moving addresses becomes difficult because the original provider controls the address allocation.

The company decides to obtain its own ASN and suitable portable IP space. It arranges an independent address block and connects to two upstream providers. It then registers the required routing objects and ROAs. After testing its BGP sessions, the company can advertise its authorized prefixes through both providers. If one connection fails, the other can continue carrying traffic.

Before independent routing	After independent routing
One main upstream	Two upstream providers
Provider-dependent addresses	Portable address space
Limited routing control	Independent routing policy
Difficult provider changes	Greater provider flexibility
Less path control	Better traffic management

This example shows why an ASN can be valuable for a growing hosting company. However, the benefits depend on proper configuration. Two providers do not automatically guarantee uninterrupted service. Your network needs suitable hardware, working routes and tested failover behavior.

Final Thoughts: Is Getting Your Own ASN Worth It in 2026?

Getting your own ASN can help your business build a more independent network. It gives you greater control over routing, upstream providers and suitable portable IP prefixes. However, registration is only the beginning. You must also manage address authorization, routing security and reliable connectivity.

For US businesses, ARIN is generally the first registry to investigate. Companies with eligible requirements in the RIPE region can explore direct membership or sponsorship through an existing LIR. Compare the costs and responsibilities before choosing either option.

This ASN Sponsoring Guide has covered the journey from registration to your first BGP announcement. Start with a clear network plan, choose the right registry and prepare your technical requirements. With proper planning, your organization can build a network that supports future growth and greater routing control.
