I am running the latest version of powerdns authoritative server version 3.3 on a Linux server. PowerDNS is using a MySQL database for it's list of resolvable sites. I need powerdns to return a specific response IP for all requests that it cannot resolve. The end result will be the user will see a specific web page for all locally unresolvable requests. How do I do that?

I had a similar problem, about setting prioritary domains, or fallbacks. Have a look : Add extra zones outside the MySQL database.

Basically, this is about setting a secondary backend. In your case, set a Bind backend in your launch clause, after your gMySQL value :

launch=gmysql,bind

If gMySQL fails, the Bind backend will have a chance to try. Create zones and records as you need them ;)

You can also use a custom backend, which always answers the same thing. You can find more about this topic on the PowerDNS backends details page.
