I'm using cable and if my FC box is plugged directly into my cable modem
(not recommend)  if I unplug my modem wait 10 seconds I would get a new
IP every time.  My firewall box stores the last IP and I get it back if
I shut it down, but I've never had it off for a long time.  You can go
to http://www.whatismyip.com/  unplug/plug  then hit refresh on your
browser and see if it changes.  Or check with your ISP.
