arp -a is not that good as you get the entire arp cache. ipconfig /all is much better as it allows you to parse data per interface.

I guess this is TIMTOWTDI, but using ipconfig /all allows you to write a reusable sub that returns all of the parsed data for you, and allows you to pick and choose which of that data you want to use. I guess I'm lazy and just do all the work up front and never have to deal with it again :)

"Nothing is sure but death and taxes" I say combine the two and its death to all taxes!

    I was not aware of the /all switch. Thanks! That's very useful.

    Just to round out the thread:

    #! Perl -w use strict; open (READ, "ipconfig /all|") or die "$!"; while (<READ>) { chomp; if (/Physical Address/) { my @pieces = split(/:/); print $pieces[1]; } } close READ;
