<p>The Internet Routing Registry (IRR) is a globally distributed routing information database.</p> <p>Established in 1995, the purpose of the IRR is to ensure the stability and consistency of Internet-wide routing by sharing information between network operators.</p> <p>The IRR actually consists of several databases where network operators publish their routing policies and routing announcements so that other network operators can use this data.</p> <p>The APNIC Routing Registry is linked to the IRR and enables Internet operators to:</p> <ul> <li>Debug routing problems</li> <li>Automatically configure backbone routers</li> <li>Perform network planning</li> </ul> <p>Users of the routing registry can query:</p> <ul> <li>Regular whois clients</li> <li>Special purpose programs, such as <a href="https://github.com/irrtoolset/irrtoolset">IRRToolSet</a></li> <li>The <a href="http://wq.apnic.net/apnic-bin/whois.pl">APNIC Whois Database web interface</a></li> </ul> <p><a href="/about-apnic/whois_search/about/what-is-in-whois/IRR/">Learn more about using the Internet Routing Registry</a></p> <h2>Why use the IRR?</h2> <h3>Benefits to networks</h3> <p>The IRR contains announced routes and routing policy in a common format that network operators can use to configure their backbone routers.</p> <p>This assists network management in a number of ways:</p> <table class="table"> <tbody> <tr> <th>Route filtering</th> <td>Traffic may be filtered based on registered routes, preventing network problems caused by accidental or malicious routing announcements.</p> <p>Routing announcement filtering can be created between:</p> <ul> <li>Peering networks where the peers agree to filter based on registered routes only. If a peer’s route is not registered, it will be filtered.</li> <li>Provider and customer networks where the provider protects its network from accidental routing announcements by its customers. The customer must register its routes before the provider.</li> </ul> </td> </tr> <tr> <th>Network troubleshooting</th> <td>Network troubleshooting A routing registry makes it easier to identify routing problems outside your network. Use the contacts for the ASN associated with the problematic route to resolve traffic problems.</td> </tr> <tr> <th>Router configuration</th> <td>Tools such as <a href="https://github.com/irrtoolset/irrtoolset">IRRToolset</a> can create router configurations.</p> <p>Use these tools to:</p> <ul> <li>Suggest CIDR aggregates</li> <li>Check aut-num objects and their routes</li> <li>Perform RPSL syntax checking on Autonomous Systems registered in an IRR</li> </ul> </td> </tr> <tr> <th>Global view of Internet routing</th> <td>If all networks registered their routes in IRRs, a global view of routing policy could be mapped. This global picture could significantly improve the integrity of global Internet routing.</td> </tr> </tbody> </table> <h3>Easier maintenance</h3> <p>Use one set of <strong>maintenance</strong> and <strong>person</strong> objects to manage both Internet resources and routing information.</p> <h3>Integrated resource and routing management</h3> <p>Before route objects can be registered in the APNIC Routing Registry, APNIC ensures the address range and AS Numbers are within APNIC resource ranges. In addition, the <strong>mnt-by</strong>, <strong>mnt-lower</strong>, and <strong>mnt-routes</strong> authentication attributes in <strong>aut-num</strong> and <strong>inetnum</strong> objects are checked to ensure the registered resource holder has control over routing objects that specify their resources.</p> <h3>Reduced costs</h3> <p>The APNIC Routing Registry service is free to APNIC Members.</p> <h3>More information</h3> <ul> <li>Visit the <a href="http://www.irr.net">Internet Routing Registry</a> for a list of Routing Registries and information on how to register a new
