XAMPP how to bind to a domain?

Question

xampp

Hello! I have two questions, help who knows, please.
In C:\windows\xampp\htdocs I threw the root of my site, went to the external IP, everything works, the site glows on the Internet by IP. But I wanted the files to be in C:\windows\xampp\htdocs\My_site and that there was a DNS for the domain, for example: ns1.my_site.ru ns2.my_site.ru.
I hope you understand what I mean.
To be more precise, I have Apache on Windows, a white IP on which the site is displayed on the Internet.
I want to specify my NS with the registrar so that he can find the site on my server.
And I want you not to have to throw the site root into htdocs.
How to figure it out?
