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.
