Appendix A. Changes from RFC 5006
The following changes were made from RFC 5006 "IPv6 Router
Advertisement Option for DNS Configuration":
o Added DNS Search List (DNSSL) Option to support the advertisement
of DNS suffixes used in the DNS search along with RDNSS Option in
RFC 5006.
o Clarified the coexistence of RA options and DHCP options for DNS
configuration.
o Modified the procedure in IPv6 host:
* Clarified the procedure for DNS options in an IPv6 host.
* Specified a sufficient number of RDNSS addresses or DNS search
domain names as three.
* Specified a way to deal with DNS options from multiple sources,
such as RA and DHCP.
o Modified implementation considerations for DNSSL Option handling.
o Modified security considerations to consider more attack scenarios
and the corresponding possible solutions.
o Modified IANA considerations to require another IPv6 Neighbor
Discovery Option type for DNSSL option.
