How to point a subdomain to third party NS servers?

Question

Domain Name System

Hey!
There is an example.com domain, it is hosted where it feels good, it has its own dns servers (ns1.example.com and ns2.example.com
) register for it ns1.host.com ns2.host.com
So, the question is: how?) this should be done with several domains.
The option to describe the desired A and AAAA record is not suitable, it is necessary to direct some subdomains to third-party DNS in order for other people to deal with them.

Answer 1

This is roughly how it should work.
ns1.hello.example.com. IN A 11.22.33.44
ns1.hello.example.com. IN NS hello.example.com.
