How to edit a server's resolver configuration

1. Access the server's command line as the root user via SSH or Terminal in WHM.
2. Open the /etc/resolv.conf file in your preferred text editor.

3. Comment out the nameserver entries you do not want by adding a # before the nameserver line.

   CONFIG_TEXT: #nameserver 192.168.0.1

4. Add the new nameserver entries.
5. Save changes and exit the text editor.

CPANEL_WARN: If you have already set up the resolver configuration via the menu in WHM, then any changes made to the /etc/resolv.conf file will be overwritten.
In addition, please note that using public DNS servers, such as Google's 8.8.8.8 and 8.8.4.4, may cause RBLs, such as Spamhaus, to not function correctly.
