Not every deployment needs its own ASN or customer-managed BGP session. The right arrangement depends on your address space, locations, availability requirements, and ability to manage routing.<\/span><\/p>\n<h2><b>Decide Whether Your Deployment Needs an ASN<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">An Autonomous System Number, or <a href=\"https:\/\/en.wikipedia.org\/wiki\/Autonomous_system_(Internet)\" target=\"_blank\" rel=\"noopener\">ASN<\/a>, identifies a network that operates under a defined routing policy. It represents the network, not an individual dedicated server. Regional Internet Registries manage public ASN assignments under their respective policies.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Most businesses using provider-assigned IP addresses do not need their own ASN. The hosting provider handles Internet routing while the customer manages the server and applications.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">An independent routing identity matters when you need to announce eligible IP space through multiple providers, maintain your own routing policy, or move infrastructure while keeping your addresses.<\/span><\/p>\n<h3><b>Compare the Three Main Arrangements<\/b><\/h3>\n<table>\n<tbody>\n<tr>\n<td><b>Arrangement<\/b><\/td>\n<td><b>Who handles announcements?<\/b><\/td>\n<td><b>Planning requirement<\/b><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">Provider-assigned IP addresses<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Hosting provider<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Confirm address allocation and network service<\/span><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">Provider-announced BYOIP<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Provider, using the agreed origin arrangement<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Confirm address rights, authorization, and delivery to your servers<\/span><\/td>\n<\/tr>\n<tr>\n<td><span style=\"font-weight: 400;\">Customer-managed BGP<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Customer routing device exchanges routes with the provider<\/span><\/td>\n<td><span style=\"font-weight: 400;\">Agree on ASN, prefixes, policies, monitoring, and support ownership<\/span><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p><b>Bring Your Own IP, or <a href=\"https:\/\/atalnetworks.com\/ko\/byoip-for-dedicated-servers\/\">BYOIP<\/a>, does not always require your own public ASN.<\/b><span style=\"font-weight: 400;\"> Some providers support announcements under their ASN or a private-ASN customer arrangement. Others require a public ASN. Confirm the actual service requirements before applying for resources or ordering hardware.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Owning or leasing an IP block also does not automatically give you unrestricted portability. Check the resource agreement and the receiving provider\u2019s acceptance requirements.<\/span><\/p>\n<h2><b>Understand BGP Announcements Before Choosing a Setup<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Border Gateway Protocol, or BGP, exchanges routing information between networks. An announcement tells another network that a particular IP prefix is reachable through a given path.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">A prefix describes an address block, such as an IPv4 \/24. A BGP session exchanges routes. It does not carry the application traffic itself.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">External BGP, or eBGP, connects different autonomous systems. Internal BGP, or iBGP, exchanges routing information within one autonomous system.<\/span><\/p>\n<h3><b>Agree on the Origin ASN<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">The origin ASN identifies the autonomous system originating the advertised prefix. It must match the intended routing arrangement and relevant authorization records.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Before deployment, establish:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Which ASN will originate each prefix.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Which device will announce and withdraw routes.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Whether the provider or customer manages that device.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">How the announced addresses reach the dedicated servers.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Who updates records during a migration.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">These decisions affect routing configuration, documentation, and incident ownership.<\/span><\/p>\n<h3><b>Separate Session Status From Working Connectivity<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">An established BGP session proves that two routing systems can exchange information. It does not prove that your prefix has reached external networks or that your application works.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">We recommend checking the full sequence: the provider accepts the route, the forwarding path exists, external networks can reach the addresses, and the application responds.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">BGP also does not automatically choose the lowest-latency path. Routing policies influence path selection, and remote networks control their own decisions.<\/span><\/p>\n<h2><b>Plan IPv4 and IPv6 Before Ordering Servers<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Address planning should cover both the IPs your servers use and the prefixes you intend to announce.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">These are different quantities. A deployment might need only a few service addresses while using a larger block for public routing.<\/span><\/p>\n<h3><b>Separate Local Routes From Internet Announcements<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">IPv4 \/24 and IPv6 \/48 are common planning boundaries for broad Internet announcement acceptance. They are not universal protocol limits.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">A provider may accept more-specific routes inside its network without advertising them globally. For example, phoenixNAP\u2019s documentation distinguishes local BGP prefixes from its global announcement requirements.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Confirm prefix-length rules with the provider rather than assuming every technically possible route will work across the Internet.<\/span><\/p>\n<h3><b>Check Control of Customer-Held or Leased Space<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Before committing to a deployment, identify who can authorize announcements and change routing records.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For leased addresses, review:<\/span><\/p>\n<ul>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Permission to announce through the intended provider.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">The agreed origin ASN.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Responsibility for <a href=\"https:\/\/atalnetworks.com\/ko\/loa-vs-irr-route-objects-vs-roa\/\">LOA, IRR, and ROA<\/a> updates.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Permitted workloads.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">What happens when the lease ends.<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">We also recommend reserving addresses for growth and separating public services from management access.<\/span><\/p>\n<h3><b>Test Both Address Families<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Dual-stack hosting needs more than an IPv6 allocation. Check IPv6 routing, firewall rules, DNS records, monitoring, and application behavior.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">A working IPv4 service can hide an IPv6 fault. Test both paths independently before publishing an AAAA record or moving production traffic.<\/span><\/p>\n<h2><b>Align LOA, IRR Records, and RPKI<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Routing paperwork and routing security records serve different purposes.

Networks decide how their routing policies handle them.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Consider a hypothetical migration. Your ROA permits the old provider\u2019s origin ASN, but the new deployment uses another ASN. If no matching authorization permits the new announcement, it can receive an Invalid state and face rejection.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Prepare and check the required records before the routing change. Keep the previous arrangement available for rollback where appropriate, then remove permissions that are no longer needed.<\/span><\/p>\n<h3><b>Keep Authorization Narrow and Accurate<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Set <\/span><span style=\"font-weight: 400;\">maxLength<\/span><span style=\"font-weight: 400;\"> according to the prefixes you actually intend to announce. Avoid granting permission for unnecessary more-specific announcements.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">RPKI checks the route origin, not every network along the path. It does not replace route filters, session protection, or operational monitoring.<\/span><\/p>\n<h2><b>Define Routing Policies and Responsibilities<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">A BGP-capable service does not necessarily include every routing feature your deployment needs.<\/span><\/p>\n<h3><b>Choose the Routes You Need to Receive<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">A default route sends otherwise unmatched traffic to an upstream provider. Selected routes provide more specific choices. A full Internet table supports broader destination-based routing decisions but requires suitable resources and ongoing management.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Do not request a full table without a clear use case.

Routing reachability, IP reputation, and geolocation are separate checks.<\/span><\/p>\n<h3><b>Review Reputation Against the Intended Workload<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Check relevant blocklists, prior-use concerns, and access to the services your application needs.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Changing the origin ASN does not automatically remove an IP address\u2019s history. A clean result from one database also does not prove acceptance everywhere.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Confirm acceptable-use rules before building a service around leased addresses.<\/span><\/p>\n<h3><b>Do Not Confuse Server Location With IP Geolocation<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Third-party databases may report a location that differs from the server\u2019s physical location or registry information.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">A geofeed or correction request can help address incorrect records. It does not guarantee immediate agreement across every database. MaxMind\u2019s correction guidance, for example, describes geofeed submissions and cases where it may not accept a requested correction.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Confirm reverse DNS control as well. PTR records, geolocation entries, and routing announcements require separate handling.<\/span><\/p>\n<h2><b>Compare Single-Site and Multi-Site Requirements<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Multiple upstream providers do not remove every failure point.

Many external networks filter those more-specific routes.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Possible designs include separate accepted prefixes, a shared anycast prefix, or provider-specific internal routing. Each requires different addressing and operational decisions.<\/span><\/p>\n<h3><b>Keep Application Recovery Separate From Routing Recovery<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">BGP can change a network path when a route disappears. It does not repair a database, copy missing application state, or restore a failed process.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">An active-passive deployment needs a working service at the recovery site. An anycast deployment needs a way to stop directing traffic to an unhealthy service.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Anycast can also move traffic between sites during routing changes. Long-lived connections and stateful applications need careful testing. Network policy, not geographic distance alone, determines which site receives traffic.<\/span><\/p>\n<h2><b>Build Monitoring and Change Control Into Deployment<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">Monitoring should cover both the routing system and the service users depend on.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Track BGP session status, prefix counts, expected origin ASN, RPKI state, and external route visibility. Add packet-loss, reachability, and application checks from more than one external network.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">A route collector or looking glass provides useful evidence, but one observation point cannot prove universal reachability.<\/span><\/p>\n<h3><b>Use a Controlled Launch Checklist<\/b><\/h3>\n<ol>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Record the current configuration and announcement state.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Confirm address rights and the intended origin ASN.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Prepare LOA, IRR, ROA, and provider filtering changes.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Check routing and management access before cutover.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Move traffic during an agreed change window.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Test IPv4, IPv6, and application behavior externally.<\/span><\/li>\n<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Keep rollback steps and responsible contacts available.<\/span><\/li>\n<\/ol>\n<p><span style=\"font-weight: 400;\">Test failures separately.
