If you have a Reseller account with us, you can register your own nameservers (ns1.yourdomain.com and ns2.yourdomain.com) to provide your clients with.
First of all, you need to obtain IP addresses to point your private nameservers to.
You can check them in an email from our Billing team or contact us in order for our Hosting team to double-check them for you.
Once you have IPs at hand, you can go ahead and register the nameservers on the side of your domain registrar.
If your domain is registered with us, follow the guidelines here.
If your domain is registered with another company, get in touch with them for the nameservers setup assistance.
Lastly, when the nameservers are registered, you need to set them up on the server:
1. Log into your main cPanel and go to the Domains section - Advanced DNS Zone Editor menu: 
2. Using the Add a Record box proceed with configuring A records for nameservers: 
3. Once done, scroll to the bottom of the page to double-check the new records: 
4. Now you need to log into WHM (yourdomain.com/whm) and set the nameservers in the Basic cPanel & WHM Setup menu in order for them to be automatically applied to all new cPanel accounts you create: 
Allow 2 - 12 hours to pass for the nameservers to propagate worldwide and feel free to use your new private nameservers.
That's it!
