Hi Tim,

I am sorry you are not here :)
Anyway, thanks for a good document.
After reading your draft, I absolutely agree to your suggestion.

As you know, our RA option draft has already considered 
both the renumbering situation and breakdown of DNS server.
 http://www.ietf.org/internet-drafts/draft-jeong-dnsop-ipv6-dns-discovery-01.txt

Like in your draft, RA-based DNS Discovery uses Lifetime field to handle these cases.

We can see the contents of Section 6.2 of ours as follows;
--------------------------------------------------------------------------------
 Step (c) : For each DNS Server option, check the following: If the 
              value of "Pref" and "Lifetime" fields is set to zero, 
              delete the corresponding RDNSS entry from both DNS Server 
              Cache and Resolver File in order to let the RDNSS not used 
              any more for certain reason in network management, e.g., 
              the breakdown of the DNS server and a renumbering 
              situation. 
--------------------------------------------------------------------------------

There is my opinion on Section 5, Solution Space of your draft.
I perfer the third to the others, because it need not any addtional functions from current stateless DHCP.
IMHO, we can inform IPv6 hosts of the change of configuration information through RA DNS option plus a hint flag.

Thanks.

Paul
