PowerDNS is only restricted by the database. We know of Oracle powered
PowerDNS installations with over 3 million domains.

The Generic Oracle backend supports master/slaving, and native. Native means
that oracle replication is used. PowerDNS does not support dynamic updates
at this time, but it could easily enough, especially on trusted networks.

Good luck!
