Subject: [mif] DNS server selection issues #3: No DHCPv6 solution:)

Hi Ted,

I thought this WG in previous discussions concluded that sending burst of DNS queries over all interfaces, and then figuring out what response to trust/use, is not a feasible approach. May require unnecessary activation of cellular radio, causes extra traffic for network, hard to determine whether to trust for validated negative or positive replies (well, maybe you could prefer the positive - but you would have to wait until all DNS servers actually reply).

Hence I don't think solutions like not trusting on NX responses, or dropping queries for private names that are sent via wrong interfaces, are feasible.

Removing local namespaces from internet is probably as feasible as removing NATs. Hence we need tools for working in local namespace scenarios.

Furthermore, we do have a charter for defining:
--

1) DNS server selection solution: a specification for describing a way for a network to communicate to nodes information required to perform advanced DNS server selection at name resolution request granularity in scenarios involving multiple namespaces. The specification shall describe the information to be delivered for nodes and the protocol to be used for delivery.

Best regards,
