dyndns and similar services map a domain name to an IP
address when they get a notification from your desktop (or
whereever the dyndns client is running) that the IP address has
changed.

If you are trying to ssh in during a time between when the IP
address has changed and when the client notifies dyndns, it will
fail.

The first questions, then:

what machine is notifying dyndns?

what software is it using for that?

how does it detect a new IP address?

how often does it run?
