Standards Track [Page 2] 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.Show full document text
