Domain Name Server Files
The -b option specifies the boot file. The default boot file is
$SYSTEM.ZTCPIP.DNSBOOT.
Lines in the files are divided into fields. If a field in the line is optional, the notation
[optional-field-value] is used. If the field is mandatory, the notation req-
field is used.
If a field must be used as specified, the field is shown as it must be used (for example,
IN means that the string IN should appear in the line in the position shown).
Boot File
The boot file is first read when NAMED starts up. This file informs the server what type
of server it is, which zones it has authority over, and where to get its initial data. The
default file is $SYSTEM.ZTCPIP.DNSBOOT. However, you can specify the name of a
different boot file on the startup command line.
The boot file consists of lines of the following format:
field-name argument ....
The various field names and the arguments are described below.
Domain
You may specify a default domain for the name server by entering a line such as the
following:
domain zone-name
For example:
domain kentcomm.com
The name server uses this information when it receives a query for a name that has no
period (.) and is unknown. When the name server receives such a query, it appends
the zone-name to the query name.
Assume that the following name is received in a query:
xyz
The result of applying the default domain is:
xyz.kentcomm.com
Primary Master
The line in the boot file that designates the server as a primary server for a zone has
the following format:
primary zone-name data-file-name
For example:
primary kentcomm.com $SYSTEM.ZTCPIP.DNSHOSTS
