Don't have specs on who to go thru, but here is a consideration. Buy the IP address from a different place that you buy the domain name from. The Management Morons at work, switched ISPs, yet the didn't tell the new ISP that they had a small domain name that also needed to be moved. So come the move, all mobile users can't get access to the mail server (and the new ISP was in no hurry to fix the problem that was our fault). The better thing would have been to have an independant domain name provider indepenant of the ISP. That way when you got the new ISP address, you go into the Domain keeper and edit the DNS yourself.
