I currently own my own domain, and have been using dyndns.com's "custom DNS" to allow me to redirect 'example.com' to my website at home, which is on a dynamic IP.

I've now switched over to a VPS solution which hosts my website and allows me root access to a box which will now host "example.com" on a static IP.

My question is, is it possible for me to somehow make "home.example.com" route to my box at home?

My suggestion (and what I do) would be to continue using DynDNS, and create a subdomain for home.example.com and make a CNAME to myhouse.dyndns.com (or whatever your DynDNS domain name is). This gives you the flexibility of using your own domain name with the ease of updating of DynDNS.

Personal example: (the .doesntexist.org address is my DynDNS address)

Brilliant. I don't know why I didn't think about using a CNAME. Cheap, too. – Eddie Parker Apr 6 '10 at 17:38
    
Awesome, just what I was looking for. – nikhil Apr 13 '14 at 16:03

BIND already supports this. The IETF standards-track RFC 2136 defines the protocol and calls it "DNS UPDATE". Apple built the "Wide Area Bonjour" part of Bonjour on this (among other things). Mac OS X has a built-in client for this, and if your version of Windows doesn't have a built-in client, you can use "Bonjour for Windows". As a bonus, you can use all the other conveniences of Wide Area Bonjour. More information at http://www.dns-sd.org/ServerSetup.html
