We have about 10 sites that we need to use https on and all the names look like this:
The domain is always the same but the subdomain is what changes. We don't own the domain but all of our sites are hosted on the same server and DNS is setup to cname our server and whenever we are going to host a new site the institution will cname our server again.
The question is, can we get a wildcard cert that will handle all the sites we have and it not interfere with some other sites that someone else has? Also, can a cert be installed on more than one server? What if we split up some of the sites and put a few on one server and a few on another?
