How to connect a subdomain to another hosting?

Question

Domain Name System

I am developing one project. The target audience of which is in search engines. Therefore, I will be engaged in SEO promotion. But after reading more about it, I learned that it is difficult to develop a project on a new domain, and search engines trust old, trusted sites more. And what will break through to a beginner is unrealistic with a new domain.
So I decided to rent a subdomain from trust sites. I have read that this can be done. But how exactly to do it? What needs to be registered in DNS to connect a subdomain to another hosting?

Answer 1

In the DNS of the subdomain, you need to register an A-record with the IP address of your server or the NS-record of your hosting. And on the hosting itself, add the same subdomain and link it to the desired site
