Hi Jimmy,

If you use port 43 whois, you can use the ! and > operators just like you
specified. A query like:

$ whois -h whois.arin.net '! > NET-99-0-0-0-1'

... would show you reassignments out of NET-99-0-0-0-1.  Please note,
however, that the result set is limited to 256 items. If there are more
than 256 reassignments, the result will truncate.

Isn't there a WHOIS command for that?
something like, er

# telnet whois.arin.net 43

or e.g.
whois -h whois.arin.net   'o > ARIN'
