NAME
resolv.conf - configuration file for name server routines
DESCRIPTION
The resolver configuration file contains information that is
read by the resolver routines the first time they are
invoked in a process. 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. At least one name server
should be listed. Up to MAXNS
(currently 3) name servers may be
listed, in that case the resolver
library queries tries them in the order
listed. The algorithm 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.
domain name The default domain to append to names
that do not have a dot in them.
address address An Internet address (in dot notation) of
any preferred networks. The list of
addresses returned by the resolver will
be sorted to put any addresses on this
network before any others.
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.
