A glue record is the IP address of a name server held at the domain name registry.
Glue records are required when you wish to set the name servers of a domain name to a hostname under the domain name itself.
For example if you wished to set the name servers of example.com to ns1.example.com and ns2.example.com you would need to also provide the glue records (i.e. the IP addresses) for ns1.example.com and ns2.example.com.
If you did not provide the glue records for these name servers then your domain name would not work as anyone requiring DNS information for it would get stuck in a loop.
Fixing your glue, by which we mean, checking the NS records in your domain's DNS zone, and making sure they match exactly the name servers being used at your registrar.
cPanel + WHM
How to change the NS records when using private nameservers.
- Login to WHM.
- Under DNS Functions, click Edit DNS Zone.
- Select your domain name from the list and click the Edit button.
- Look to the right of "SOA" and replace the nameserver with your primary private name server (ns1, be sure to include the trailing dot).
- Look to the right of "NS" and replace each nameserver with your private name servers (ns1 and ns2, be sure to include each trailing dot).Â
- Scroll down and click the Save button.
Be sure this is done for every domain name you host.
Plesk 10
Login to Plesk, and go to the desired domain's control panel (if not already there). Under "Websites & Domains", click the "DNS Settings" link. Next to the domain, click the "[Manage]" link.
Here you can edit the existing NS records, or add a new NS record if needed.
Plesk 9
Login to Plesk as the admin user. At Home, click the "DNS Settings" link. Here you can edit the existing NS records, or add a new NS record if needed.
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. (See "DNS Update").
