sink.arpa question

[Ted Hardie <hardie () oakthorn com>]

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
