What is the Internet Routing Registry?
The IRR is a way for ASN’s to publicize their own intended routing policies without having to request a change from a go-between. The RAdb which stands for the Routing Arbiter Data Base, which is part of the IRR, is part of a joint project between Merit and ISI. The Routing Arbiter is a project of the US National Science Foundation. As part of that project, it runs a routing registry database. That database (the RAdb) forms part of the IRR collection of databases. The RIPE database is not part of the RAdb but does participate in the IRR. At present, there are five entities that contribute to the IRR effort and more are expected. Today, all the contributing registries use the RIPE-181 database format. All IRR participants can be contacted via automail handlers that accept batch updates via email.
