Tommy,

Wearing no hat at all, isn't this 6to4 address issue completely orthogonal to DDR SVCB or even to ADD ? I.e., IMHO let's not mention anything about 6to4 addresses in our WG documents, else should we also say something about IPv6 ULA ? :-)

Regards

Subject: [Add] DDR and 6to4

What does everyone think about actively discouraging the use of 6to4 addresses in the DDR SVCB records? I know this is covered by RFC7526; is that sufficient for us to omit text in DDR? Should we reference it and require resolvers to not provide those addresses? It seems there are some edge cases where a client and resolver may disagree about the nature of a given IP address if these are designated.

Thanks,
Tommy
