Technical Summary There is some known misbehavior of DNS authoritative servers when they are queried for AAAA resource records. Such behavior can block IPv4 communication which should actually be available, cause a significant delay in name resolution, or even make a denial of service attack. This memo describes details of the known cases and discusses the effect of the cases. Working Group Summary This document is a product of the dnsop working group. Protocol Quality David Kessens reviewed this document for the IESG.
