> The NOTIFY message will trigger the slave to send an SOA request to the Master, and an XFER will start if the serial number is higher. In effect it shortcuts the refresh time countdown. This behavior can be turned off with the 'notify no' directive in named.conf.

Specifically, my question is:

Does the slave connect to the master, or viceversa (when either the
timeout or a NOTIFY message is triggered)?  Which protocol is used for
that connection?
