I've used bind's nsupdate in the past to do something like this (not on dynamic ip change, but on provisioning vms but quite similar). It was some time ago but, iirc the provisioning scripts uploaded some file like this: update add $FULL_DNS_NAME. 300 A $INT_IP send and then executed nsupdate. I guess you can do something similar with cron jobs. But there's probably an easier/more reliable option. Hope it helps.
