As Internet backbone connectivity becomes more complex, it has increasingly become more difficult to keep track of peering policies between providers and customers.

The Internet Routing Registry (IRR) is an evolving network database of Internet registered routes and routing policies. By specifying routing details using Routing Policy Specification Language (RPSL), IRR providers can use the information to check consistency and build router configurations.

This tutorial covers the importance and benefits of the IRR to Internet operations and introduces participants to the tools used to interact with the IRR. The session will also explain what routing objects are, how they are created, and how to register and query them.
