There is some known misbehavior of DNS authoritative servers when they
are queried for AAAA resource records.  Such behavior can block IPv4
communication that should actually be available, cause a significant
delay in name resolution, or even make a denial of service attack.
This memo describes details of known cases and discusses their
effects.

This document is a product of the Domain Name System Operations
Working Group of the IETF.
