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.
