Internet Routing Registry
open-in-new
<p>An Internet Routing Registry (IRR) is a database of <a href="/facts/Internet/Xw1rVvJU">Internet</a> route objects for determining, and sharing route and related information used for configuring routers, with a view to avoiding problematic issues between <a href="/facts/Internet_service_providers/dUacAxef">Internet service providers</a>. </p><p>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. Network engineers from participating organizations are authorized to modify the <a href="/facts/Routing_Policy_Specification_Language/gkJSrUMR">Routing Policy Specification Language</a> (RPSL) objects, in the registry, for their own networks. Then, any network engineer, or member of the public, is able to query the route registry for particular information of interest. </p>
