If your domain name is registered with Register.com, please follow these steps to update your nameservers:
First login into your Register.com account
In your account dashboard, go to Domains and click Manage
Select the domain name you wish to connect with UENI, then hit Manage
Scroll down to nameserver settings towards the bottom of the screen
Click in the corresponding blank fields to add the nameservers we've provided
Click on Continue to confirm your nameserver changes.
Once you have updated your nameservers, there will be 24-48 hours of DNS propagation time during which your website and email may not be available.
