My experience has been that STATIC IPs GENERALLY cost 10 to 15 times more than the domain registration itself.I checked mine to refresh my memory. (And boy, do they hide it thoroughly, How did I ever find it in the first place?!) A static IPv4 currently goes for $5.99/month, or 3-4 times domain name registration ($19.99/year); static IPv6 is free. It would be pretty nervy to charge for IPv6, since there are something like a billion IPs for every person on the planet.
