jcwren (whose nick I CONTINUALLY mistype as 'jcrewn') suggested I define the limits of this function. It takes domain names, dotted IP addresses, and large decimal numbers. It RETURNS dotted IP addresses though.

require "IPsort.pl";  # assuming that's where you put it
@IPs = IPsort(qw(
  12.43.12.65 48.23.6.1 4.1.64.23 www.bergen.org 84394239
));
