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 contain
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).
