Question How to use subdomain when domain hosted elsewhere

[Corobori]

Hi,
I have got a domain name, let's call it mydomain.com, hosted with a provider, running a custom solution that is without Plesk, where it is working as a www.mydomain.com and also with mail.mydomain.com pointing to a mail server. This works just fine.

What I want to do now is a demo site for another system I am starting to use. But those demos site will be running with another provider where I am running the latest Plesk for Window.
I am expecting to make it working as myshop.mydomain.com and adminmyshop.mydomain.com, both of them pointing to a separate space on that server. I contacted my provider's support and to my surprise, and disappointment, the answer was that it wasn't possible. Is that true ?

The main thing here is to configure the DNS correctly. If you can add A records for your subdomains that will point to the address of your Plesk server, then you will get what you want.

I am fine with the DNSs. How do I define in Plesk those entries ? I wanted to add them as a subdomain (shop.mydomain.com) but as the root domain’s name doesn’t exist on Plesk I am not allowed to choose it. Or should I before add the main domain name (mydomain.com) in my Plesk even though it won’t actually used on that server ?

It should be done on DNS server where the main zone file of your domain is located but not on Plesk side.

I know the DNSs should be changed on the DNS Server, which is done. But now it is how to inform my Plesk where to go.
