This section explains how to configure which nameserver to use when resolving IP addresses to hostnames and vice versa. It does not explain how to configure the system as a name server.
To manage DNS entries, you can add, edit, or remove DNS names from the
/etc/resolv.conf file. A sample file is given below:search com nameserver 204.11.126.131 nameserver 64.125.134.133 nameserver 64.125.134.132 nameserver 208.185.179.218
The search key specifies the string which will be appended to an incomplete hostname. Here, we have configured it to com. So, when we run: ping ubuntu it would be interpreted as ping ubuntu.com.
The nameserver key specifies the nameserver IP address. It will be used to resolve a given IP address or hostname. This file can have multiple nameserver entries. The nameservers will be used by the network query in the same order.
| If the DNS server names are retrieved dynamically from DHCP or PPPoE (retrieved from your ISP), do not add nameserver entries in this file. It will be overwritten. |
