Master Server db.domain Files

All other resource records must use the canonical name instead of the actual host

name.

WKS

Well Known Service records. The WKS record describes the services provided by a

particular protocol on a particular interface. The protocol is any entry in the

/etc/protocols file. The list of services is as specified in the host’s /etc/services file.

You can specify only one WKS record for each protocol for each address.

Mail Exchanger records. MX records specify a list of hosts to try when mailing to a

destination on the Internet. The

MX data indicates an alternate host or list of hosts

that accept mail for the target host if the target host is down or inaccessible. The

preference field specifies the order a mailer must follow if more than one mail

exchanger exists for a given host. A low preference value indicates a higher

precedence for the mail exchanger.

In the example db.div file, mail for rabbit must go to rabbit.div.inc.com first. If rabbit

is down, its mail must be sent to the host

indigo.div.inc.com.

$TTL

Indicates (in seconds) the time-to-live (ttl) value for records that do not have the

ttl value defined in the data field.
