Getting an AS number
An AS number is your own identity in the global routing table — the prerequisite for announcing your own addresses and choosing your own upstreams.
When you need one
You need your own AS number when you want to run BGP yourself: announce your own address space, connect to more than one network, and control your own routing policy. If you are happy for us to route your traffic, you do not need one — it is the step up to being your own network.
How you get one
AS numbers come from the regional internet registry, usually through a sponsoring member such as us. You will justify the need — typically multihoming — and provide the registry details. We handle this regularly and can sponsor and guide the application; it pairs naturally with getting your own address space and bringing your own IP.
What running it involves
An AS number is a commitment as much as an asset. You will maintain your routing registry records, sign your routes with RPKI, filter what you announce (prefix filtering) and keep your BGP sessions healthy. We are here for the parts you would rather not run alone — see multihoming.
