I need to secure a domain
example.com and subdomains,
I didn't set up the server so I don't really know the DNS entries. As you may notice I'm really new to this. I noticed that example.com and the subdomains dash.example.com, sql... don't have the same IP address and not the same web host. So are they really subdomains?
Can I still purchase a certificate for www.example.com and use ServerAlias of virtual host of Apache to secure the subdomains? Or should i purchase a wildcard certificate for *.example.com and somehow add example.com to the virtualhost?
It may be a bit confusing as I don't really know what i'm talking about so please understand!
