The Refresh parameter in the SOA record of a zone tells the slave
servers how often they should query the master server to see if the
serial number has increased. If it has, they'll perform a zone
transfer. If NOTIFY is enabled, the master server will notify the
slaves whenever a zone is updated, and they'll do a zone transfer
immediately.
