Well first things first: Yes it is entirely possible to achieve a
dyndns-style DNS Update Service with PowerDNS Server.
As for the dynamic dns update protocol (
http://en.wikipedia.org/wiki/Dynamic_DNS#RFC_2136_dynamic_DNS_update ) this
is not supported by pdns.
Secondly however i fear there is not much official documentation other than
and documentation of such implementations although quite common according
to what i've heard on the web are scarce.
If you have done a bit of web programming however chances are that you
already know how to update a mysql database using a cgi (probably php)
script and do basic authentication before accepting anything from a
Thats actually all you would need to update the IP address of an IN A
record in PowerDNS Server if you're using the gmysql backend.
you indepth information on what PowerDNS asks the DB about and what the
