Domain glue records, also known as nameserver glue records, are DNS records that associate a domain name with its corresponding IP address when the nameservers for that domain are located under the same domain name. They are necessary when the authoritative nameservers for a domain are within the same domain itself.
Typically, when resolving a domain, the DNS system looks up the IP addresses of the domain’s nameservers by querying the top-level domain (TLD) nameservers. However, if the nameservers are within the same domain, a circular dependency is created, as resolving the IP addresses of the nameservers requires querying the nameservers themselves.
To resolve this circular dependency and provide the IP addresses of the domain’s nameservers, domain glue records are used. Here’s an overview of how to create domain glue records:
- Determine the IP addresses: Identify the IP addresses of the nameservers that you want to associate with your domain. These IP addresses should correspond to the servers where your nameservers are hosted.
- Contact the domain registrar or DNS provider: Reach out to your domain registrar or DNS provider that manages the authoritative DNS records for your domain. They should have a control panel or management interface where you can manage your DNS settings.
- Access DNS management interface: Log in to your DNS management interface provided by your registrar or DNS provider. This is where you can add, edit, or delete DNS records for your domain.
- Locate the nameserver records: Look for the existing nameserver records for your domain. These records specify the domain names of your nameservers.
- Add glue records: In the DNS management interface, find the option to add or edit glue records. Typically, this involves adding an “A” (Address) record that associates the domain name of each nameserver with its corresponding IP address.
- Enter the glue record details: Provide the necessary information, including the domain name of each nameserver and its associated IP address. Ensure accuracy when entering the IP addresses and domain names to avoid any errors.
- Save the changes: Once you have entered the glue record details, save or apply the changes in your DNS management interface. The glue records should now be created and associated with your domain.
It’s important to note that creating and managing domain glue records might require administrative access to the authoritative DNS servers or coordination with your domain registrar or DNS provider. The exact process and availability of glue record management may vary depending on your specific DNS provider’s interface and policies.
If you are uncertain or require assistance, it’s recommended to contact your domain registrar or DNS provider’s support team for guidance on creating and managing glue records for your domain.
