okay sysadmins gies a hand here

so my hosting provider said that I can set up a pleroma instance (it's not a normal hosting provider or a data center and they have their own infastructure) on their servers.

my domain currently points to their server, call it "A". they told me I should set it up on server "B". I want the pleroma instance under a subdomain. How would I set up a subdomain on server B while still keeping the domain pointed to server A? I've never done domain stuff before
