Abstract:

   This document provides guidelines and documents Best Current Practice
   for operating authoritative DNS servers, recursive resolvers and stub
   resolvers in a mixed IPv4/IPv6 environment.  This document recommends
   that both authoritative DNS servers and recursive resolvers support
   IPv4 and IPv6.  It also provides guidance on how recursive DNS
   resolvers should select upstream DNS servers, including when
   IPv4-embedded IPv6 addresses are available.

   This document obsoletes RFC 3901.
