title: What exactly does "every SSL certificate requires a dedicated IP" mean?
body: <p>I've read a bit about SSL certificates, and in particular I've read that an SSL certificate "requires a dedicated IP address". Now, I'm unsure of the meaning of this; does it mean that the certificate requires a dedicated IP address separate from the IP address used for normal HTTP communication, or just that it can't share the IP address with other SSL certificates?</p>
  
  <p>To clarify, I have a VPS with a dedicated IP address. The VPS is hosting quite a few different sites, including several subdomains of the main site, but only the main site and the subdomains requires SSL. Can I simply purchase an SSL certificate for <em>*.example.com</em> using my current IP address, or do I need to get one that is separate from the other sites on the VPS? Or even worse, do I need to get one that is separate from all HTTP traffic on the server? Keep in mind that none of the other sites needs SSL.</p>
  
  <p>Thanks for any clarification on the topic.</p>
