IRR是一组全局分布的数据库，应用服务器可以在其中注册它们的路由和地址相关信息。通常认为，IRR数据的质量是不可靠的，因为很少有经济动机促使asa及时注册和更新其路由信息。为了验证这些消极的信念，我们对BGP中的（IP前缀及其源AS）对与IRR中注册的相应信息进行了全面的分析，反之亦然。考虑到BGP和IRR的实践，我们提出了一种方法来匹配IRR和BGP之间的（IP前缀，origin AS）对。我们观察到，用IRR注册IP前缀和原始域名的做法很普遍。然而，IRR数据的质量可能因路由注册中心、区域Internet注册中心（AS所属）和AS类型的不同而有很大差异。我们认为，考虑到这些观察结果，IRR可以使BGP路由器有选择地依赖相应的IRR数据，从而有助于提高BGP路由的安全性。
The IRR is a set of globally distributed databases with which ASes can register their routing and address-related information. It is often believed that the quality of the IRR data is not reliable since there are few economic incentives for the ASes to register and update their routing information timely. To validate these negative beliefs, we carry out a comprehensive analysis of (IP prefix, its origin AS) pairs in BGP against the corresponding information registered with the IRR, and vice versa. Considering the BGP and IRR practices, we propose a methodology to match the (IP prefix, origin AS) pairs between the IRR and BGP. We observe that the practice of registering IP prefi xes and origin ASes with the IRR is prevalent. However, the quality of the IRR data can vary substantially depending on routing registries, regional Internet registries (to which ASes belong), and AS types. We argue that the IRR can help improve the security level of BGP routing by making BGP routers selectively rely on the corresponding IRR data considering these observations.
