Overview:
The Resolver Configuration interface allows you to use a configuration wizard to edit the /etc/resolv.conf file. This file contains the NameServers that your server queries to resolve domain names into IPv4 or IPv6 addresses.
Now another window with the text boxes to edit the resolver IP addresses will come up. You need to click on the button Proceed and you will be lead to the next page where you need to digit in the desired resolver IP addresses. As we’ve seen earlier, it will edit the /etc/resolv.conf file.
Configure resolvers:
Your server requires at least two resolver IP addresses. You can also add an optional third address.
Step 1: Login to WHM
First, you need to login to the WHM. You could login to the WHM by appending the WHM port to the hostname of the server or IP address of the server. (Please note: hostname needs to be pointed correctly to the server to use the hostname to connect to the WHM).
An example is given below.
Eg: https://server.domain.com:2087
(Please replace the server.comain.com with the hostname of the server or IP address of the server)
Step 2 Go to the Resolver Configuration in WHM
After logging into the WHM, you need to go to the Resolver configuration. You could locate it under the Network Setup. You could also find the feature by making a search on the top left search box.
To configure a third resolver, enter that IP address in the Tertiary Resolver text box.
Click Continue. A confirmation message will appear.
