resolv.conf - configuration file for domain name system resolver
DESCRIPTION
The resolver configuration file contains
information that is read
by the domain name system resolver library the first time
it is invoked in a process.
It is only necessary to create this file to specify
an explicit default domain name other than the default one derived
from the
domainname.1
command, or to specify name servers to use on other machines.
The file is designed to be human readable
and contains a list of
keyword-value pairs that provide various types
of resolver information.
keyword value
The different configuration options are:
- nameserver address
-
The Internet address (in dot
notation) of a name server
that the resolver should query.
Up to
MAXNS
(currently 3) name servers may be listed. In that
case the resolver library queries tries them
in the order listed. The policy used is to
try a name server, and if the query times out,
try the next, until out of name servers, then
repeat trying all the name servers
until a maximum number of retries are made.
If there are no
nameserver
lines in this file, then the loopback address is used, so there
must be a name server running on the same machine.
- domain name
-
The default domain to append to names that do
not have a dot in them, and used in searches. If there is no
domain
line in this file, then it is derived from the domain set by the
domainname.1
command, usually by removing the first component.
For example, if the
domainname.1
is set to ``foo.podunk.edu'' then the default
domain used by the resolver will be ``podunk.edu''.
The is the same policy used by
sendmail.8
The keyword-value pair must appear on a single line,
and the keyword (for instance,
nameserver)
must start the line. The value follows
the keyword, separated by white space.
