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 memo provides information for the Internet community.
