RESOLVER(4)                     Domain/OS SysV                     RESOLVER(4)



NAME
     resolver - resolver configuration file

SYNOPSIS
     /etc/resolv.conf

DESCRIPTION
     The resolver configuration file contains information that is read by the
     resolver routines the first time they are invoked by a process.  The file
     is designed to be human-readable and contains a list of name-value pairs
     that provide various types of resolver information.

     This file is required on any system using the name server daemon, named,
     either locally or remotely for Internet name-address resolution. The file
     must reside on any host running named locally, but only a single line --
     the domain keyword followed by the domain name -- is required. If the
     host is not running named locally, the file is a link to /etc/resolv.conf
     on the TCP/IP administrative host and must contain both the the domain
     keyword, followed by the domain name, and the nameserver keyword,
     followed by the IP address of the remote name server(s) that will answer
     the local host's name queries.

     The two configuration keywords are:

     nameserver   Followed by 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.  If no nameserver
                  entries are present, the default is to use the name server
                  on the local host.  (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       Followed by a domain name that is the default domain to
                  append to names that do not have a dot in them. If no domain
                  entries are present, the domain returned by gethostname(2)
                  is used (everything after the first ``.''); if no domain is
                  returned, the root domain is assumed.

     The name value pair must appear on a single line, and the keyword (e.g.
     nameserver) must start the line.  The value follows the keyword,
     separated by white space.
