in thread Accessing NIC/mac address ?

update: arp gets the MAC address of the gateway or router of your network. I should just shut up.

Same basic idea for Win NT/2000 except you would use 'arp -a' what Rex(Wrecks) says in place of the ifconfig read

    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;
