How to Get Your Own ASN
Obtaining your own Autonomous System Number (ASN) allows you to participate in global BGP routing, establish peering relationships with ISPs, and announce your IP address space to the internet independently. The process involves applying through your Regional Internet Registry.
Como Funciona
ASNs are allocated by the five Regional Internet Registries: ARIN (Americas), RIPE NCC (Europe/Middle East), APNIC (Asia-Pacific), LACNIC (Latin America), AFRINIC (Africa). To qualify, you typically need: (1) a demonstrated need for BGP multihoming — connecting to 2+ upstream providers; (2) an IP address allocation of at least a /24 IPv4 or /48 IPv6; (3) a technical justification explaining why a private ASN won't suffice. You apply through an LIR (Local Internet Registry) member of the RIR, or directly for ARIN.
Por Que Importa
Having your own ASN gives you routing independence — you can change ISPs without renumbering, establish direct peering at internet exchanges, and have full control over how your traffic enters and exits the internet. It is essential for organizations running multihomed networks or internet infrastructure.
Problemas Comuns
- Application rejected due to insufficient technical justification
- No existing IP allocation — RIRs require you to already have address space
- Confusing LIR membership requirements with direct RIR membership
- Ongoing membership fees overlooked in budget planning
