Hey, Jason,

There's likely a better way to do this, but something sleazy like this 
works:

=-=-=-=-=
#!perl

use Sys::Hostname;

($name,$aliases,$addrtype,$length,@addrs) = gethostbyname(&hostname);

($a,$b,$c,$d) = unpack('C4',$addrs[0]);

$ipaddr = "$a.$b.$c.$d";

print $ipaddr."\n";
=-=-=-=-=

More likely than not, your script would let you use $addrs[0] in its 
un-unpacked state.  (I'm assuming that you really only need the IP 
address and not info about a specific TCP socket).

Good luck,
