Step 1.
To enable Plesk Onyx for your domain, login to your Internic account and click on Domain Manager.

How do I enable Plesk on a domain registered elsewhere?
Alternatively, you can purchase Plesk Onyx without having a domain at Internic. Once you have purchased the Full Control Hosting package, you will set new nameservers to your domain to connect it to Plesk.

Step 1.
Login to your Internic account and click Full Control Hosting, or hold your mouse over Email & Hosting and select Full Control Hosting. 

Step 2.
Click the button to Get Started Now. 

Choose your server location and purchase term (monthly or yearly) in the shopping cart, then check I agree to the Terms and Conditions, and click Process Order. 

Step 3.
To connect your domain, log into the Hosting Manager of your account. To the far right of your Full Control Hosting package, click the down arrow beside the Control Panel button and Add Domain.

Step 4.
Login to Plesk Onyx by clicking the Control Panel button to the right of your domain.

In the Plesk control panel beneath your domain name, click on DNS Settings.

Copy the IP addresses associated with your domain's unique ns1 and ns2 records (for example, they may look like ns1.internicexample.com, 123.45.678.90, and ns2.internicexample.com, 12.345.67.890).

Step 5.
Login to your domain registrar's account and create registry nameservers for your domain using the information you obtained in your Plesk Onyx DNS Settings. Apply these to your domain.
