I'm sorry for the weird question title, but I don't know how to describe the problem in just a few words. I accept suggestions for new title.

Here is my issue, or actually I am not experienced enough in server administration to understand/solve it myself.

I have a server at IP X
I have a domain mydomain.com purchased from a hosting company
I want to create DNS server ns1.mydomain.com
I want mydomain.com to use ns1.mydomain.com DNS server

How I can set ns1.mydomain.com to use IP X and it's DNS server to serve DNS requests when I cannot set IP as DNS record for ns1.mydomain.com in the hosting company control panel.
Should I first use my hosting company's DNS hosting insert A record for mydomain.com to point to IP X and then setup subdomain (I guess) ns1.mydomain.com where I can place my DNS server.

Illustration of the scheme:

Domain mydomain.com using NS ns1.mydomain.com points to IP X
But how to set ns1.mydomain.com to point to IP X

Edit:

The answer

Quote from Alnitak:

You only need glue records when the hostname for your nameserver is part of the same domain as it's trying to serve.

Glue records are published in the parent zone. Hence if the operator of example.com wanted to have nameservers named ns1.example.com and ns2.example.com then the .com domain would need something like:

example.com.     IN NS ns1.example.com.
                 IN NS ns2.example.com.
ns1.example.com. IN A  192.0.2.1
ns2.example.com. IN A  198.51.100.5

(example subnets taken from RFC 5737).

The child zone would usually have the same A records in it (even if only for consistency), but when they're in the child zone they're not technically glue records any more.

Whenever I've needed to do such a thing I've always needed to contact my domain host to do this, although Xilo have added the functionality to set your own NS server IP's in the control panel, so yours may have this if they're good!
