Multi-Subdomains Re: Multi Domains Plugin

Hi Everyone
Can I use the multi-domains plugin to create a multisite based on subdomains? and if so what is the best way of setting it up?

For example: I wish to allow blogs to be created under subdomain1.Mainsite.com, subdomain2.Mainsite.com etc...

I have set up some subdomains using the multi-domains plugin input fields and they are offered on the sign up page ..and blogs can be created under the subdomains.. so that looks promising.

However, I was expecting to find a blog at subdomain1.Mainsite.com and subdomain2.Mainsite.com. As I am not sure how to set up A names and C names under DNS I may have that wrong or maybe I am trying to do something that the plugin isn't designed for.
