There are a couple of different dynamic ip address to hostname services out there..

*free ones that I've used

Here's a HUGE listing..

Folks using raw ip addresses are dragging down the sig generator script. Please please please get a dynamic host set up so that we can all keep our cool sigs.

If you're having trouble setting these services up, post here- I can't guarantee that we can fix the problem, but we'll be glad to try.
