I'd just like to add to this excellent answer...If you've just got a list of IP addresses to sort -- not two IP addresses plus a country -- here's how you'd do it: `print map{sprintf(("%d.%d.%d.%d")."%s\n",(split/,/)\[0..3\])} sort map{sprintf"%3d,"x4,(split/\W/)\[0..3\]}` [download] It took a lot of scratching my head to adapt this, so I thought I'd save the next person the trouble. Hope it's useful!	[reply] [d/l]
