-The [Internet Routing Registry (IRR)](http://www.irr.net/index.html) is a globally distributed database of routing information. The IRR contains announced routes and routing policies in a common format, and network operators use this information to configure their backbone routers.

 The IRR consists of many individual [routing registries](http://www.irr.net/docs/list.html), and some are managed by regional entities, such as APNIC, ARIN, and RIPE. Each routing registry contains IRR entries that provide information about IP prefixes and the [autonomous systems](https://www.cloudflare.com/learning/network-layer/what-is-an-autonomous-system/) authorized to announce them.
 
 To announce your subnet prefixes, Cloudflare requires accurate IRR entries for your prefixes and autonomous system numbers (ASNs).
