RE: PPP ext for IPv6 dns address

[juha.wiljakka at nokia.com]

Hi,

This is a very good question, more details can be found in this draft
that is currently in RFC Ed. queue:
http://www.ietf.org/internet-drafts/draft-ietf-dnsop-ipv6-dns-configurat
ion-06.txt
 
Also see: RA-based mechanism (personal submission):
http://www.ietf.org/internet-drafts/draft-jeong-dnsop-ipv6-dns-discovery
-05.txt
 
Furthermore, many OS'es (e.g. Symbian, according to my understanding
also Microsoft, ...) implement well-known site-local addresses (as a
last resort mechanism) for IPv6 DNS discovery, see e.g.:
http://www.tahi.org/conformance/ct-profile-host/dd/DDWellKnown.html
 fec0:000:0000:ffff::1 
 fec0:000:0000:ffff::2 
 fec0:000:0000:ffff::3 

This is the expired draft:
http://www.ietf.org/proceedings/03mar/I-D/draft-ietf-ipv6-dns-discovery-
07.txt
 
BR,
       Juha Wiljakka

		I was looking into the RFCs for the PPP extension that
allow the server to include IPv6 DNS addresses on the PPP response.

		I found out that there was a draft,
draft-ietf-pppext-ipv6-dns-addr-01.txt, that proposes this option. But
this draft was droped.

		Is there any solution to pass DNS addresses to the
client without using DHCPv6? Is there any option for PPP that could be
used?

	You should be able to use neighbor discovery on the PPP link
although it's not as simple as using IPV6CP.
