How to make a hidden redirect from a domain to a hosting without a frame and without changing the url?

Question

URL Handling

There is a domain franziska-kimme.de and other hosting.
The problem is that when entering a domain name in the company, there is only either a direct redirect, but then the url changes, or an indirect redirect from franziska-kimme.de to the desired hosting, but all the data is in the frame. That is, I open a domain, and it substitutes a frame with the address of my hosting - it turns out full well---a.
Zero indexing, zero meta tags (they are all in a frame) - in short, nonsense. Tech support clearly didn't say what to do to have a domain url and download data from the hosting "as is" without any frames. Somehow through DNS.
Can someone tell me what to do? Bo Google does not index at all. And the frame in the site is in this case complete nonsense
