The fields used in the db.cache file are (lines beginning with a semicolon (;) are
comments):
name
For NS records, name specifies the name of the domain served by the name
server listed in the data column. A period (
.) in the name column represents the
root domain (the root of the DNS name space hierarchy).
For A (address) records, the name column contains the name of the name server
whose address appears in the data column.
ttl
The optional time-to-live (ttl) indicates how long (in seconds) a server caches the
data received in response to a query.
class
The optional class field specifies the protocol group. The protocol group IN, for
Internet addresses, is the most common class. If you do not specify this field, the
class defaults to the last class specified. All the entries in the example db.cache file
are of class
IN.
type
Records of type NS list the name servers. The first field in an NS record is the
domain for which the name server has authority. The last field in an
NS record is
the fully qualified name of the name server. For records of type A list, the first field
in an
A record is the name of the name server. The last field in an A record is the
Internet address of the name server.
