Example 33.5 Zone Entry for other-domain.de
zone "other-domain.de" in {
};
The zone options:
type master;
By specifying master, tell BIND that the zone is handled by the local name
server. This assumes that a zone file has been created in the correct format.
type slave;
This zone is transferred from another name server. It must be used together with
masters.
type hint;
The zone . of the hint type is used to set the root name servers. This zone defini-
tion can be left as is.
file my-domain.zone or file "slave/other-domain.zone";
This entry specifies the file where zone data for the domain is located. This file is
not required for a slave, because this data is fetched from another name server. To
differentiate master and slave files, use the directory slave for the slave files.
masters { server-ip-address; };
This entry is only needed for slave zones. It specifies from which name server the
zone file should be transferred.
allow-update {! *; };
This option controls external write access, which would allow clients to make a
DNS entry—something not normally desirable for security reasons. Without this
entry, zone updates are not allowed at all. The above entry achieves the same be-
cause ! * effectively bans any such activity.
