Dynamic DNS isn't built into PowerDNS itself, but it can be written very
easily as a standalone application, imagine this:

You're running PowerDNS with the generic MySQL, Postgress, ODBC or SQLite 
(or some other database driven backend).

You write an application (the DynDNS server) that just waits for DNS 
updates to come
in. When it receives one it just connects to the same database where 
retrieves it's data from and updates the information.

PowerDNS will then use these updated values automatically.

How you implement the DynDNS server and client is up to you.
