soa.xfer

If the soa table contains a column named xfer and DNS-based zone transfers are enabled See Zone transfers, the xfer column will be examined whenever a DNS-based zone transfer request is received.

The xfer column should contain one or more IP addresses separated by commas. These IP addresses will be allowed to transfer the zone. If the xfer column is empty, no DNS-based zone transfers will be allowed for that zone. The IP addresses may contain standard wildcard characters. Thus, if you want to grant zone transfer access for a particular zone to any IP address, you would set xfer=*.

The xfer column may be any size you want, and whatever size you think will be adequate for the IP address lists you intend to use.

To create an xfer column on your soa table, for example, you might issue SQL statements like this:

mysql> ALTER TABLE mydns.soa ADD COLUMN xfer CHAR(30) NOT NULL;
