Each of the database files consists of a series of entries, or resource records. The syntax of these records is always as follows:
reference [TTL] class type value
The following describes each part of a record:
* reference. The reference to which the record refers. This can be a domain (or subdomain) or a standalone computer (name or IP address).
* TTL. The Time-To-Live value for the record. If this is not present, a default TTL value is used. This determines how long other name servers store this information in their cache.
* class. The class of the record. For TCP/IP networks, this is always IN (internet).
* type. The type of the record.
* value. The value of the record. The value depends on the type of record.
