Follow these steps to use your own domain name as a nameserver for websites your server hosts.

Log in to WHM using root for your username and your server's password at https://yourserverip:2087, where yourserverip is your server's IP address.

Below DNS Functions, select Edit DNS Zone. Select the domain name you want to use, and then select Edit.

For the two rows with the menu displaying NS, edit the right-most columns to ns1.your domain name. and ns2.your domain name., respectively.

Note: Don't forget the period character (".") after your nameserver in these fields.

In the Add New Entries Below this Line section, do the following in the first row:

        First field: Type ns1
        Second field: Type 14400
        Third field: Select A
        Fourth field: Type your server's IP address

Then, in the second row, do the following:

        First field: Type ns2
        Second field: Type 14400
        Third field: Select A
        Fourth field: Type your server's IP address

Select Save.

Note: DNS can take 24-48 hours to propagate once these changes have been made.
