AXFR FAQ

This page describes the PowerDNS Server AXFR functionality and how to configure it.

Please note that not all PowerDNS Server backends support master or slave support, see if your favorite backend supports those at the appendix sections A1 through A13 at http://doc.powerdns.com/ .

General documentation on Master and Slave support is available at https://doc.powerdns.com/md/authoritative/modes-of-operation/.

Master

Don't forget to enable master-support by saying master=yes in pdns.conf or PowerDNS Server will not send NOTIFYs whenever you change/update a zone.

In Master mode PowerDNS Server will send NOTIFYs to all Nameservers that are listed as NS records in the Zone if it is a Master Zone.

Slave

Don't forget to enable slave-support by saying "slave=yes" in pdns.conf or PowerDNS Server will not poll Master Nameservers for SOA changes or accept NOTIFYs from them.

In Slave mode PowerDNS Server listens for NOTIFYs from the master IP for zones that are configured as slave zones and will also periodically check for SOA serial number changes at the master.
