There is one unique difference. If you have a Class C address, and reserve a domain through Internic, it is easy to specify what DNS server that domain should use. If you Get a Class C address, and wish to host the in-addr.arpa you are at the *mercy* of your upstream provider's technical support team. It took Verio 3 months to corrently configure their DNS servers to slave off of my DNS server. Tips (based purely on my situation, your's may be different): 1) My upstream provider insists on doing reverse DNS, so they have to be set up as a slave to my master DNS server. 2) The NS field in your in-addr.arpa record is important. The upstream provider may not be able to pull your records unless they have an NS field in your reverse lookup record. eg: IN NS ns.YOURUPSTEAM_PROVIDER.com This is true for forward as well as reverse lookups.
