is there a way to have Plesk host a subdomain only without hosting the www address and/or adding the subdomain as a ServerAlias ?

I've seen a couple threads on this but no definite answers.

 

Anyone? Is this possible?

 

Presumably the DNS is hosted elsewhere and you're pointing the subdomain at your Plesk server, which is why you want to configure the subdomain only.

Have you tried just adding a domain as sub.domain.com?

If I add a domain called domain.co.uk then plesk creates www.domain.co.uk and domain.co.uk. I don't have to create co.uk first and run domain.co.uk as a subdomain.

Have't tried it but I don't see why it wouldn't work.
