Originally I had the server at home and on Comcast so I used dyndns.org for DNS.

Once the server got a bit more popular, I leased a server at a colo facility. They set up the server name in their DNS so I didn't really have any reason to manage my own DNS. DynDNS was managing the domains and I had a reverse lookup for the server so mail was being delivered.

Recently I upgraded server to a more powerful server and this time they didn't add the server to their DNS. When I asked them about it, they offered to manage my DNS for me for a few bucks per domain or they'd delegate it to me.

I checked DynDNS and they'll manage the reverse lookup but it's a few extra bucks. May as well have the ISP manage it as it's a few bucks less if I go that way.

But I've administered bind in the past for entire address ranges so rather than pay someone else to manage it, I'd rather do it myself. Both to save a few bucks but also to keep my fingers in DNS management.

So I got my domain files set up without a problem but I'm not sure how to set up a reverse lookup file for a single or two addresses. I want to make sure it's right before I flip the switch so I thought I'd drop a quick note here and see what sort of response I get
