What are Glue Records

From Dashboard > Domains > YOURDOMAIN.COM > Glue records

What is a Glue Record (or Additional record)?

A glue record (or additional record) is an A Record (or IP Address) assigned to a domain name or subdomain. It helps break circular DNS lookups or ‘impossible dependency’.

When do you need a glue record?

Glue records are particularly important when the nameservers (eg. ns1, ns2) for a domain name (eg. domain.com) are the subdomains of the domain name itself.


Domain name: mydomain.com
Nameservers: alfred.cloudflare.net, jessie.cloudflare.net

No Glue Record required

Domain name: mydomain.com
Nameservers: ns1.mydomain.com, ns2.mydomain.com

Glue Records required for ns1.mydomain.com and ns2.mydomain.com

Setting a Glue Record

If you are providing your own authoritative nameservers we can provide Glue Records as your domain Registrar. This is an expert function for those who are comfortable managing their own authoritative nameservers. Simply enter nameserver domain names and IP addresses, as required.
