HP-UX IP Address and Client Management Administrator's Guide HP-UX 11i v2, HP-UX 11i v3

type The start of authority (SOA) record designates the start of a domain and indicates that
this server is authoritative for the data in the domain.
The NS record designates a name server for the current origin
(0.0.127.in-addr.arpa).
PTR records are usually used to associate an address in the in-addr.arpa domain
with the canonical name of a host. The PTR record in the example db.127.0.0 file
associates the name localhost with the address 1, that is,
1.0.0.127.in-addr.arpa. (The current origin 0.0.127.in-addr.arpa is
appended to the 1 in the name field because it does not end with a dot.)
data For an SOA record, data includes the name of the host this data file was created on,
the mailing address of the person responsible for the name server, and the following
values:
Serial
Indicates the version number of this file, incremented whenever you
change the data.
Refresh
Indicates (in seconds) how often a slave name server must update
its data from a master server.
Retry
Indicates (in seconds) how often a slave server must retry after an
attempted refresh fails.
Expire
Indicates (in seconds) how long the slave name server can use the
data before it expires for lack of a refresh.
Minimum ttl
Indicates (in seconds) the minimum number of seconds the name
server is allowed to cache data. After the ttl (time to live) value
expires, the name server must discard the cached data and obtain
new data from the authoritative name servers.
The NS data is the fully qualified name of the name server.
The PTR data is the loopback address of localhost, in the in-addr.arpa domain.
$TTL Indicates (in seconds) the time to live value for records that do not have the ttl value
defined in the data field.
Master Server db.domain Files
A master server has one /etc/named.data/db.domain file for each domain for which it is
authoritative. domain is the first part of the domain specified with the -d option in the
hosts_to_named command. This file must contain an A (address) record for every host in the
zone.
The following is an example db.div file:
; ; db.div ; $TTL 86400
@ IN SOA rabbit.div.inc.com root.moon.div.inc.com (
1 ; Serial
10800 ; Refresh every 3 hours
