Perl Monger solution:

ifconfig | perl -ne '/dr:(\S+)/||next;(/127\.0\.0\.1/)||print"$1\n"'

Density is good. I'm hoping to win one of the cookies Vincent mentioned
in under an hour of labor. -grin-

In addition to making the world a far better place by authoring yet
another craptastic filter for ifconfig output, I thought I'd go into
shameless self-promotion mode and mention that the Omaha Perl Mongers
have a new website:

   http://omaha.pm.org/

Join our mailing list and come to our first meeting in years, to be held
April 1! Drink some beer, learn some Perl. You know you want some
software on that beefy server of yours. Perl is here for you. It can do
anything*.

Linus called me and specifically said *you* should join our list and
come to our meeting. Don't let him down. -grin-
