DNS Problems with Subdomains

[ZeroEnna]

Hey there,

I wanted to fix a problems I recently encountered. I wanted to use subdomains. So for example: sub.example.com refers to example.com/sub

However, the DNS is not resolving this construction.

My domain address has a A- and MX-Record pointing to my server, and I can't create subdomains within my providers account. So how do I manage to get this working?

Kind Regards

Zero
