Silly question: how well would using 1.0.0.257.in-addr.arpa match the need identified in draft-jabley-sink-arpa ?
It seems like it would be equally well guaranteed to be non-existant (short of change in the def of IPv4 and in-addr.arpa). Like sink.arpa, it would get you a valid SOA and nothing else. Am I missing something, or is this operationally equivalent? regards, Ted
