RDNS is controlled by whoever controls you IP addresses. Typically it's your ISP - few people with org of the size that people on this list have own their own IP addresses.
Talk to your ISP and tell them what you need. Heck, it's probably a good idea to do it permanently anyway, as long as the addresses on your cable connection are static. It doesn't hurt to have the redundancy.
