The zone Statement
The zone statement is used to define a zone as master, slave, stub or
hint.
NOTE Previous releases of BIND used the term primary for a master zone,
secondary for a slave zone, and cache for a hint zone.
The following are the zone types:
master - This is the master copy of the data in a zone.
slave - A slave zone is a replica of a master zone. The master 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 is written to the file
specified. HP recommends that you use a file, because it speeds the
server startup and prevents unnecessary wastage of bandwidth.
stub - A stub zone is similar to a slave zone, except that it replicates only
the name server records of a master zone instead of the entire zone.
hint - The initial set of root name servers is specified using a hint zone.
Upon startup, the server uses the root hints to find a root name server
and gets the latest list of root name servers.
Specifying Access Limitations
You can specify access limitations for the zone in the zone statement.
You can control the following types of accesses:
• Updates
• Queries
• Transfers
You can also specify access controls globally using the options
statement. See the section Access Control Options in “The zone
Statement” on page 27, for more information.
zone Statement Syntax
After the keyword zone in the zone statement, specify the name of the
zone in quotes, then specify the data class followed by the statements
enclosed in braces.
