Hi pfg,

> Yes, you can get certificates for any subdomain combination. Note that you will have to pass the domain ownership challenge for each domain separately (i.e. passing the ownership challenge for [simonbell.com](http://simonbell.com) does not automatically allow you to get certificates for any subdomain of [simonbell.com](http://simonbell.com)).

If i list [ventureone.com](http://ventureone.com), [docs.ventureone.com](http://docs.ventureone.com), [mail.ventureone.com](http://mail.ventureone.com), [sales.venture.ventureone.com](http://sales.venture.ventureone.com) in the certificate request how can i pass the domain ownership challenge? Would all of these domains have to map to the same server IP and would the request to be made from that server?

Thanks.
