resolv.conf(4) resolv.conf(4)NAME resolv.conf - configuration file for resolver routines DESCRIPTION /etc/resolv.conf (if present) enables host-name look-up from the Berkeley Internet Name Domain (BIND) name server, named. The /etc/resolv.conf file contains information that locates the name server; this information is read by the resolver routines (described in resolver(3N)) the first time they are invoked in a process. The file contains a list of keyword-value pairs that provide various types of resolver information. Each keyword-value pair must appear on a single line that begins with the keyword. The keyword and value must be separated by a space or a tab. Here are the recognized keywords and their values: address address Specifies an Internet address (in dot notation) of any preferred network. The list of addresses returned by the resolver routines is sorted so that addresses specified by this keyword appear before any others. domain name Specifies a domain name to append to names that do not contain a dot. This value defaults to the domain set by the domainname command. nameserver address Specifies the Internet address (in dot notation) of a name server that the resolver routines should query. At least one name server should be listed. Up to MAXNS (currently three) name servers can be listed. If /etc/resolv.conf contains more than one name server, the resolver routines query each in the order listed. If the query times out, the next name server is queried until the list is exhausted. The resolver routines then repeat the cycle, trying all the name servers, until reaching a maximum number of retries.
