IP Based virtual hosting with dedicated IP for SSL cert?

Ok, I'm going to take a guess that I just need to follow the Tutorial "SSL Certificates with Apache 2 on Ubuntu 12.04z" and use Wildcard certificates, which states: "as they are signed for multiple hostnames and therefore can be used to provide SSL service for multiple sites using a single IP address".

That said, is there any other distinct advantage to having unique IP's for other sites?

Thanks.

If you have multiple domains - i.e. example.com and mysite.com - you need seperate certificates and as such seperate IPs. If you want www.example.com, sub1.example.com and mail.example.com - all subdomains of example.com - you can use a wildcard certificate.

There are techniques such as SNI to use multiple SSL certificates on one IP. But if your userbase exists out of people that still use Win. XP that might not be an option, since it doesn't support SNI iirc. See: https://en.wikipedia.org/wiki/ServerNameIndication
