Once you purchase your cPanel VPS with us, one our Technical Support staff will contact you to walk you through setting up the nameservers as this is part of the installation required by us to finalize the VPS setup process.
To have your own nameservers for your own domain (i.e.: ns1.yourdomain.com / ns2.yourdomain.com) you must complete the below 2 steps:
Step 1- To create the nameservers to point to the VPS IP you purchased from us, you will need to register ns1 and ns2 to the IP(s) we will provided you. You are more than welcome to provide us with temporary credentials for us to perform this task for you at your domain registrant if it's complicated or you are not familiar with the process.
Step 2- Once the nameservers are registered (step 1), it's now safe to change the domain nameservers to point to your custom made ones, which is ns1.yourdomain.com and ns2.yourdomain.com.
