Glue records are special DNS records that bind an NS server name to its IP address at the parent zone level. They are needed when you want to use NS servers inside your own domain.
\n
Why you need them
\n
Say you want mycompany.tj to be served by ns1.mycompany.tj and ns2.mycompany.tj. A chicken-and-egg problem appears: to find the IP of ns1.mycompany.tj, you’d have to ask ns1.mycompany.tj first — but we don’t know where it is yet.
\n
The solution is a glue record: the .tj registry stores a “hint” with your NS server’s IP, and that hint is returned along with the delegation.
\n
When glue records are needed
\n
- Your own NS inside your domain (typical for registrars and hosts)
- Whitelabel DNS for your business clients
\n
How to add one
\n
In the Navju Cloud panel for a .tj domain:
\n
- Open the domain’s management page
- Go to Child NS
- Enter the name
ns1.mycompany.tjand its IPv4 - Save — the request is processed by the .tj registry within an hour
