An Internet Routing Registry (IRR) is a database of Internet route objects for determining, and sharing route and related information used for configuring routers, with a view to avoiding problematic issues between Internet service providers.
The Internet routing registry works by providing an interlinked hierarchy of objects designed to facilitate the organization of IP routing between organizations, and also to provide data in an appropriate format for automatic programming of routers.
Then, any network engineer, or member of the public, is able to query the route registry for particular information of interest.
Most global ASNs provide valid information about their resources in their e.g. AS-SET[8] objects.
Peering networks are highly automated, and it would be very harmful for the ASNs.
