Considerations for Internet Routing Registries (IRRs)
and Routing Policy Configuration
Abstract
The purpose of this document is to catalog issues that influenced the
efficacy of Internet Routing Registries (IRRs) for inter-domain
routing policy specification and application in the global routing
system over the past two decades. Additionally, it provides a
discussion regarding which of these issues are still problematic in
practice, and which are simply artifacts that are no longer
applicable but continue to stifle inter-provider policy-based
filtering adoption and IRR utility to this day.
