I am not very familiar with dynamic DNS, and was curious if I could get it to work for a certain use case.
I have a few Raspberry Pi's I'm setting up for mocking server setups of applications we use at a small scale of our larger setup. They have wireless access capability. I'd like to be able to throw them in a bag and work with them using my laptop in various settings. However, working out the IP's and addresses every time to communicate with them on new networks would be quite annoying (having to change the endpoints all of the applications/configurations are referring to).
I can have normal DNS A Records point to internal IPs and they work great while on private networks. However this is less ideal for changing IPs. Would I be able to use Dynamic DNS to resolve the DNS records to internal addresses? (Such that connecting to a new wireless network all of the lookups would work after everything is connected without having to monkey with the router, custom dns server, etc.)
Initial research indicates Dynamic DNS usually resolves to the external IP whereas in this case I wish to automatically resolve to the address obtained on a specific interface for each client e.g. Eth0.
