Technical Summary

   This document specifies IPv6 Router Advertisement (RA) options
   (called DNS RA options) to allow IPv6 routers to advertise a list of
   DNS recursive server addresses and a DNS Search List to IPv6 hosts.
   It obsoletes RFC 6106 and allows a higher default value of
   the lifetime of the DNS RA options to avoid the frequent expiry of
   the options on links with a relatively high rate of packet loss.

Working Group Summary

The working group preferred to work on a bis version to replace RFC 6106, instead of producing an RFC
to update RFC 6106.

Document Quality

There are several implementations of RFC6106 and these implementations will most likely be updated pretty quickly after this document is published
