What NS should be specified for the domain when using DNS hosting?

Question

Domain Name System

The situation is as follows:
The domain has ns from selectel
NS1.SELECTEL.ORG
NS2.SELECTEL.ORG
NS3.SELECTEL.ORG
NS4.SELECTEL.ORG
I rented a VPS from company X, I bought DNS Hosting from them with ISP Domain Manager
in the settings I specified NS selectel

Will such a link work?

Answer 1

Why do you need DNS hosting? Your domain is already hosted. If you bought DNS hosting in a new location, then specify the new location with the NS registrar

Answer 2

The answer to the question is that you need to specify those NS that contain the actual DNS records of your DNS zone.
Where you will store them, with which operator, is purely your business. The main thing is that the domain registrar has up-to-date NS servers registered.
