secure domains/subdomains

I have a question about mod_ssl, and secure domains...
I know that every unique address you register as secure requires a
certificate(yes it is extortion)
so http://arhosting.com requires a certificate registered with that
address, and secure.arhosting.com requires a seperate certificate
registered if I want to do sercure things on both domains seperate...

but what I don't know, is that if just like virtual hosts(which for
apache, that is what a subdomain is) do I have to have a seperate ip for
the main domain, and the subdomain, that is seperate...?

My apache vitual hosts entries look like this now:



DocumentRoot /home/arhosting.com/web
ServerName arhosting.com
ServerAlias www.arhosting.com

AllowOverride All




for per domain ip addresses, would I have to go to an ip in the
field?
and can that ip be used for subdomains also that need secure certs?

I think I know the answer to this already....each virtual domain needing
it's own ip address for certs...(domains, and subdomains), but I just
want to verify.
