Usually SSL certificate installation requires a dedicated IP address to be assigned to your domain name. This is how SSL works - it requires a unique IP for a virtual host entry of the domain name the certificate is being installed for. Before installing an SSL certificate you need to be sure that the domain name resolves to the unique dedicated IP which is not used for any other Certificate installation.
You may also check with your Hosting Company if SNI technology is available on your server. If so, you will be able to install an SSL Certificate on a shared IP without ordering a dedicated one.
Please pay attention to the fact that there are a few issues that may occur.
If your domain is hosted with us, you may ask our Support team to use SNI for your SSL installation. Alternatively, you will be suggested to use a dedicated IP.
