Abstract

As currently specified by the IETF, ipv6 address assignment policy is planned to be strictly along topological lines. While this approach offers a high degree of routing aggregation, the fact that topology is determined by ISPs means that addresses assigned in this manner will not be portable, severely constraining end customer choice. In reaction to this, the various RIRs are proposing non-topological, or "provider independant" address assignment. Unfortunately, without changes to the ipv6 protocol to implement a scalable routing and addressing architecture, principally by de-coupling the "locator" and "endpoint id" properties of addresses, such a change is likely to result in the creation of a new, substantially large "routing swamp" that could eventually cause global routing state explosion, stability, and convergence issues. This fundamental flaw in ipv6 badly needs to be resolved if it is to succeed in widespread deployment.
