In the network where I work we have frequent situations where people setup a virtual to try something new out and want to tell others (within the same network) about their experiments.
For this kind of situation I would like to introduce an additional (sub)domain and let these people hook a hostname to their virtual similar to what internet based services like DynDNS do. I.e. the virtuals have a script that periodically updates their dns entry as they may have gotten a new IP from the internal DHCP server.
So far I've been unable to find a 'ready to run' opensource solution (for me it should run on Linux) that can simply be installed on the LAN. (I'm probably no using the the right search terms.)
I did find this http://nexus.zteo.com/blog/your-own-dynamic-dns-in-3-steps/ but that requires giving the key to update the entire domain to everyone in the LAN.
What solutions have I missed ? Or writing up my own implementation the real way to go?
