What is a Glue Record?
As we learned in our article What Are Domains?, a domain is associated with an IP address. That IP directs visitors to the correct location on the Internet that hosts your website and its contents. In the same way, glue records or nameserver glue records, link a nameserver on the internet to an IP address. When a DNS request is made for an IP address of a specific domain, it's queried at the registrar. The registrar will provide any information that it has for the DNS. If there is a glue record, it is presented as the place to look for any DNS zones.
