There aren't any .ARPA hosts any more, but this might not be a bad idea
for hosts in .MIL, since many of those still do not use the domain name
system and probably never will.  That way, at least you'd be able to
correspond with them.

We STILL rewrite outgoing mail from UCSD as user%localhost@ucsd.edu
because of this; there are quite a few instances where ucsd.edu being
the only campus host in the NIC hosts table has prevented people from
communicating unless they used this form.

I don't believe .csnet exists any more either.  That's obsolete and probably
can be deleted.  As I recall, all csnet hosts went to real domain names
a while back.
