multidomain certificate and IPs


I have one VPS with a IP. I have 8 domain running on that box. I would like to buy multi-domain certificate. So my question, do I need 8 different IPs (single dedicated IP for each domain)?

For Multi Domain SSL Certificates, you would only need 1 IP address.

You can watch a Comodo Video that explains it for you.

Thank you! helped greatly

Is there any advantages/disadvantages having 1 IP or having multiple IP?
