Subdomain configuration

hi all!

Can I config subdomain to www.subdomain.domain.tld, or only subdomain.domain.tld?
If I can config this 2 version too, how can I config this?

Now I have 1 subdomain, and I linked to the 1 user webdir, but that solution don't let the www.subdom.dom.tld.

Can You understand me?
Thanks

You can have both. Just make sure that their DNS records point to the correct IP address.
