resolv.conf is the name of a computer file used in various operating systems to configure the Domain Name System (DNS) resolver library. The file is a plain-text file usually created by the network administrator or by applications that manage the configuration tasks of the system.
Purpose
In most Unix-like operating systems and others that implement the BIND Domain Name System (DNS) resolver library, the resolv.conf configuration file contains information that determines the operational parameters of the DNS resolver rou
Contents and location
The resolv.conf file typically contains directives with the IP addresses of nameservers available to a host.
resolv.conf is usually located in the /etc directory of the file system.
Sometimes it is necessary that the contents of this configuration file be managed by multiple agents or programs. For this purpose the resolvconf program is available to manage such operations in a conflict-free manner.
