Yup, dynamic DNS updating sounds like what you want. I've never set it up
or used it myself but I do know there are some security issues (i.e. if
incorrectly setup almost anyone could send you update information).
One way to do this would be to keep the master file for domain.com on
ftp.domain.com . Then once you are online you have a script that edits
the file locally and SCP's it across to domain.com and performs a
"ndc reload". You would also need to edit the serial number as well.
