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. 

keywordvalue

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.  This defaults to the domain set by the domainname(1) command. 

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.
