I assume those BOFs were for IPv4? When considering DNS discovery in IPv6 context, we need to consider the scope of such discovery -- ie. where it is expected to be used, and possible subsequent configuration methods. As I see it, DNS discovery can either be: 1) "all that you need" 2) "the first step" In the first model, you need no other information. When you've completed DNS discovery, that's it. This is a very valid scenario in e.g. mobile environments, when visiting networks (for example, at IETF's, I run dhcpv4 *only* to get the DNS address :-( ). In the second model, you generally want to obtain also other information. This typically applies to non-visiting networks, like an enterprise LAN. The question becomes which tool is used (or fits best) in getting that information. If you need/want to use DHCPv6 (stateful or stateless) for that, no use having a separate mechanism for DNS and the rest. The critical thing in the 2nd model is whether DNS resolvers enable some config mechanisms: they certainly enable being able to surf to the home page of your own (or enterprise) from where you can obtain some values, scripts which give you the configuration you want etc. But perhaps more importantly, you could place configuration details in the DNS, in some format. So, basically if one believes roaming users or DNS-based configuration would be nice, some easy DNS resolver configuration mechanism would be "very nice". -- Pekka Savola "You each name yourselves king, yet the Netcore Oy kingdom bleeds."
