How to configure custom nameservers

This article shows how Nexcess clients with Dedicated, VPS, or Reseller accounts can configure custom nameservers, provided Nexcess was the registrar for their domain. 

Attention: Use this procedure only if Nexcess was the registrar for your domain. If Nexcess was not the registrar, contact that registrar's support team for assistance.

Stage 1: Register nameservers 

  1. Log in to the OpenSRS control panel. If you require login information, refer to your Nexcess Welcome Email.
  2. Scroll down the screen and click Domain Locking. The Domain Locking screen will display in red text whether your domain is currently Enabled or Disabled.
  3. If your domain is currently set to Enable (Figure 1), click Disable and Submit.

  5. Scroll to the bottom of the window and click If you want to create or modify a name server based on domain name, click here.
  6. Under the New host name column, click inside the text boxes and type over the current host names with your custom host names and click Save Configuration

Stage 2: Configure nameservers in NodeWorx

  1. Log in to NodeWorx.
  2. Specify the primary, secondary, and tertiary nameservers as necessary (Figure 2):

  3. Click Update

Stage 3: Add A records

After specifying your nameservers, create an A record for each one.

  1. From the NodeWorx main menu, click System Services > DNS Server > Zones.
  2. Click Records next to the domain name servers you registered.
  3. From the Add a new:  drop-down list, select A, then click Go (Figure 3).
