RE: [FWP] IP address regex golf

["Tony Payne" <gssintl@flashcom.net>]

This is certainly beatable.

$f='(\d+)\.';/^$f$f$f(\d+)$/&($1|$2|$3|$4)<256

I'd like to shorten it by moving the <256 test into the regex, using the
(?()...) construct, but can't seem to get it to work.  Has anyone headed
down that road yet?

I'm thinking something along these lines:
$l='(\d+)(?($+>255)die)';/^$l\.$l\.$l\.$l$/

Btw, where can we find more information on the golf tourney?  Do you have to
attend TPC to enter?
