resolv.conf(5)							File Formats Manual						    resolv.conf(5)

Name
       resolv.conf - resolver configuration file

Description
       The  resolver  configuration  file, contains information that the resolver routines read the first time they are invoked by a process.  The
       resolver file contains ASCII text and lists the name-value pairs that provide various types of resolver information.

       The file is required if your system is running BIND.  This file must contain the BIND domain name for the local area network.  If your sys-
       tem is a BIND client, this file must also contain nameserver entries.

       There are two entry formats for the file:

       domain binddomain
	      This  line  specifies  the  default  domain to append to local host names.  If no domain entries are present, the domain returned by
	      after the first dot (.) is used.	If the host name does not contain a domain, the root domain is assumed.

       nameserver address
	      In this entry, the address is the IP address, in dot notation, of the BIND server that should be queried to resolve  host  name  and
	      address  information.   You should have at least one name server listed.	Two or more name servers reduces the possibility of inter-
	      rupted BIND service in the event that one of the servers is down.  You can list up to (10) name servers.	If more than one server is
	      listed,  the resolver library queries you to try them in the order listed.  If no name server entries are present, the default is to
	      use the name server on the local machine.

	      The algorithm used is to try a name server, and, if the query times out, to try the next, until out of name servers or the query	is
	      resolved.   The  last step is to repeat trying all the name servers until a maximum number of retries has been made or the query has
	      been resolved.

       The name value pair must appear on a single line, and the keyword or must start each line.

Examples
       The following is an example of a file:
       ;
       ; Data file for a client
       ;
       domain	      cities.us
       nameserver     128.11.22.33
       Lines beginning with a semicolon (;) are comment lines.
