Simple and to the point. Truth be told I've always wanted something like this for my own domains, so that I can point to a home machine, but was too lazy to set it up. Thanks for throwing this out here!

You're welcome.

Initially it was put together as a learning experience, but I can see that it is useful enough to remain live indefinitely.

I can imagine several way of monetizing it, such as adding the MX/SRV/TXT/CNAME records, etc. But the one that seems most useful would be allowing custom domain - and sadly I can't see how to do that easily.

(I can't imagine somebody would trust me with their root-domain, basically. And having *.foo.example.com seems like it would be long enough to spoil the utility.)

The “root-domain” is the domain name with a single zero-length label at the top of the hierarchy. What you're referring to is a zone.

I thought context would make that clear, but yes you're correct.

Nice! Setting up my server to update every hour was as simple as: crontab -e and adding the line: 31 * * * * curl http://dhcp.io/set/99351a76-f6... (the above job will run on the 31st minute of every hour)

Do you really want to have to wait up to an hour if your IP address changes and you're away from home?

Yes it is from the context that I inferred what you're talking about. I didn't mention it to pick, but because the DNS is littered with misunderstandings and I think that's part of what holds it back.

Cool.

I suspect that you'll want to hide STDOUT, if not STDERR. If you're ever dual-homed you might also want to consider adding an explicit "-4", or "-6" in there.
