Definition and Usage (Zone Types)
master The master copy of the data in a zone.
slave A slave zone is a replica of a master zone. The masters list specifies one or more IP
addresses that the slave contacts to update its copy of the zone. If file is specified, then the
replica will be written to the file. Use of file is recommended, since it often speeds server
startup and eliminates a needless waste of bandwidth.
stub A stub zone is like a slave zone, except that it replicates only the NS records of a master
zone instead of the entire zone.
hint The initial set of root nameservers is specified using a hint zone. When the server starts up,
it uses the root hints to find a root nameserver and get the most recent list of root
nameservers.
NOTE Previous releases of BIND used the term primary for a master zone, secondary for a slave zone,
and cache for a hint zone.
Class
The zone’s name may optionally be followed by a class. If a class is not specified, class in is used.
Options
check-names See Name Checking.
allow-query See the description of allow-query in the Access Control section.
allow-update Specifies which hosts are allowed to submit Dynamic DNS updates to the
server. The default is to deny updates from all hosts.
allow- transfer See the description of allow-transfer in the Access Control section.
max-transfer-time-in See the description of max-transfer-time-in in the Zone Transfers
section.
notify See the description of notify in the Boolean Options section.
also-notify also-notify is only meaningful if notify is active for this zone.
The set of machines that will receive a DNS NOTIFY message for this
zone is made up of all the listed nameservers for the zone (other than the
primary master) plus any IP addresses specified with also-notify.
also-notify is not meaningful for stub zones. The default is the empty
list.
