.TH RESOLV.CONF 5 .SH NAME resolv.conf \- Domain Name System resolver configuration .SH SYNOPSIS .B /etc/resolv.conf .SH DESCRIPTION .de SP .if t .sp 0.4 .if n .sp .. The .B /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: .PP .RS .ta +15n nameserver \fIIP-address\fP .br domain \fIdomain-name\fP .RE .PP 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 .B /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 .B nonamed name server can't look beyond the local network. .PP 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. .PP The long version of this story can be found in .BR resolver (5). .SH FILES .TP 20n /etc/resolv.conf DNS resolver configuration file. .SH "SEE ALSO" .BR resolver (5), .BR hosts (5), .BR nonamed (8), .BR boot (8). .SH AUTHOR Kees J.
