To update your domain's Nameservers, please follow these steps:  

Step 1.
Login to your Internic account and click Domain Manager.

Step 2.
Click directly on your domain name to access the domain editing page.

Step 3.
Once you are on the domain editing page, select the DNS tab. In the drop-down beneath Nameserver Information select Use Third Party Hosting. Enter your nameservers in the two boxes provided, or update the current nameservers you see. You can also delete extra nameservers by clicking on the red X, or add new ones by clicking on the green + sign.

Step 4.
Once you are done editing your nameservers, scroll down to the bottom of the page and click Save Changes.

Troubleshooting

Please note, nameservers will never have a period (.) at the end. If your domain currently has a hosting package or email package with Internic you will first need to cancel the hosting. To cancel a hosting package, please go to the Hosting Manager. To cancel a Weebly Website, please go to your Website Manager.
