Abstract
This document defines the changes that need to be made to the Domain
Name System (DNS) to support hosts running IP version 6 (IPv6). The
changes include a resource record type to store an IPv6 address, a
domain to support lookups based on an IPv6 address, and updated
definitions of existing query types that return Internet addresses as
part of additional section processing. The extensions are designed
to be compatible with existing applications and, in particular, DNS
implementations themselves.
