resolv.conf - Domain Name System resolver configuration
The /etc/resolv.conf is used to configure how the host will use the Domain Name System to resolve hostnames to IP addresses. It may con-
tain these two lines:
The nameserver entry tells the IP address of the host to use for DNS queries. If it is set to 127.0.0.1 (which is the default) then the
local name daemon is used that may use the /etc/hosts database to translate host names. You normally only need a nameserver entry if the
name server is at the other side of a router. The default nonamed name server can't look beyond the local network.
The domain entry tells the default domain to use for unqualified hostnames. This entry is usually not given in which case the domain of
the local host is used.
The long version of this story can be found in resolver(5).

resolv.conf - resolver configuration file
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:
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.
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
The name value pair must appear on a single line, and the keyword or must start each line.

Lines beginning with a semicolon (;) are comment lines.
