I think you mean Dynamic DNS updates (TSIG can be used for different 
things, e.g. AXFR)

Unfortunately, I believe the BIND backend is not one of those which 
supports DDNS:


See also:



Because this backend retrieves its configuration from plain files and 
not a database, the HTTP API is unable to process changes for this 
backend. This effectively makes the API read-only for zones hosted by 
the BIND backend."

This doesn't specifically mention DDNS updates, but does say it's 
effectively read-only.

One option is to import your BIND zone files into one of the database 
backends to powerDNS.  Another option is to keep BIND as a hidden 
primary, and then slave powerDNS from it.
