My point is simply that what we say about DNS should be compatible with
what we say about routing.
I think we must consider how little influence any RFC has on operational behavior, as opposed to the much greater influence they have on implementations.
IMHO, the best we can say is ULAs SHOULD NOT be returned in DNS responses to hosts that cannot reach those addresses and then give some guidelines on how to do this correctly in practice.
and how are you going to determine the "reachability" between the two endpoints based on a name/address lookup?
are you nuts? the DNS has zero idea of the topology between the node making the query and the node information the query
is requesting.
