Gap Analysis for IPv4 Sunset
draft-ietf-sunset4-gapanalysis-09
Abstract
Sunsetting IPv4 refers to the process of turning off IPv4
definitively. It can be seen as the final phase of the transition to
IPv6. This memo enumerates difficulties arising when sunsetting
IPv4, and identifies the gaps requiring additional work.
