DNS Glue

Step 3 of 3 of setting up private name servers,

Make sure your SOA and NS Records are Correct

This article is all about fixing your glue, by which we mean checking the SOA and NS records in your domain's DNS zone, and making sure they match the name servers being used at your registrar exactly.

The SOA (Start of Authority) and NS (Name server) records tell the internet that your private name servers are authoritative and contain the most up-to-date information about your DNS settings. If these are not set correctly, some DNS servers will not trust your private name servers. Other DNS servers may get confused because there is a mismatch between what the registrar says and what your name servers say. This typically results in some people being able to reach your domain, while others cannot. So it is always a good idea to double-check these settings:

Note: Hatchling, Baby, Business, Personal, and Enterprise plans cannot use private name servers, so there is no need to worry about the glue on those plans.

Fixing the Glue

Depending on your hosting plan, the instructions for how to make the proper changes for your DNS Glue will vary. Please refer to the proper section below with instructions for your specific control panel.

cPanel + WHM

The following steps will walk you through how to change the NS records when using private name servers with WHM and cPanel.

  1. Log in to WHM.
  2. Under the DNS Functions section, click Edit DNS Zone.
  3. Select your domain name from the list and click the Edit button.
  4. In the SOA field, replace the name server with your primary private name server (ns1... - be sure to include the trailing dot):

  5. In the NS  field, replace each name server with your private name servers (ns1 and ns2, - be sure to include each trailing dot):

  6. Scroll down and click the Save button.

Be sure this is done for every domain name you host.

Plesk 10 and Higher

The following steps will show you how to change the NS records when using private name servers with Plesk version 10 or higher.

  1. Log in to Plesk.
  2. Go to the desired domain's control panel (if not already there).
  3. Click on the Websites & Domains tab.
  4. Click the DNS Settings link:

  5. Next to the domain, click the Manage link if applicable:

Here you can edit the existing NS records by selecting the host entry, or add a new NS record if needed:

Updating A Records

After your name servers have been created and the glue is set, if you are using private name servers, then you must add the necessary A records to your domain.

If you have not updated the A records accordingly, please refer to the following knowledge base article for a basic walkthrough on how to achieve this:
