Do you need an SSL for each domain?
3 Answers. SSL certificates verify the domain or hostname, not the IP address. However, most web servers and browsers now support Server Name Indication (SNI) and Subject Alternative Name (SAN) which means you don’t need a second IP address. For that matter you don’t need to buy certificates any more.
