RFC 6106 IPv6 RA DNS Options November 2010
1. Introduction
The purpose of this document is to standardize an IPv6 Router
Advertisement (RA) option for DNS Recursive Server Addresses used for
the DNS name resolution in IPv6 hosts. This RA option was specified
in an earlier Experimental specification [RFC5006]. This document is
also to define a new RA option for Domain Name Search Lists for an
enhanced DNS configuration. Thus, this document obsoletes [RFC5006],
which only defines the RA option for DNS Recursive Server Addresses.
