A Glue Record is the registration of a nameserver hostname and it’s static IP (IPv4 & IPv6) with the registry [.COM, .ORG, .CA, etc]. In order for hostnames to be used as nameservers and delegated to a domain name, it is necessary to establish a glue record.
For example, dns1.easydns.com is a registered nameserver hostname.
IPv4 Glue records dns1.easydns.com. 172800 IN A 126.96.36.199
IPv6 Glue records dns1.easydns.com. 172800 IN AAAA 2400:cb00:2049:1::a29f:1835
Users now have the ability to add their own glue records for name servers directly from within their easyDNS account. However please note that users can only do this for domains that we’re the registrar for.
To add glue records please do the following:
1.Log into your easyDNS account
2. Click on the MANAGE link for your domain
3. Click on GLUE under DOMAIN SETTINGS
4. Enter your name server, the new IP address, and click on NEXT
5. Confirm your changes
You should now be able to do a WHOIS on your name server and have results that look like the following:
Server Name: NS1.EASYDNSDOMAIN.NET
IP Address: 188.8.131.52
Registrar: easyDNS Technologies Inc.
Registrar WHOIS Server: whois.easydns.com
Registrar URL: http://www.easydns.com
