Do I have to have a dedicated IP, to have a SSL certificate?

Having a SSL certificate on your domain used to require a dedicated IP address. Luckily, this is no longer the case.

Shared & Reseller Hosting

Our cPanel Linux Hosting, and Plesk Windows hosting both support SNI (Server Name Indication). This technology allows web server to host multiple domains, with SSL certificates, without the need for a dedicated IP address!

VPS & Dedicated Servers

Our VPS’s and Dedicated Servers can be setup to support SNI (Server Name Indication). Wither or not your server supports SNI depends on the software and configuration you are currently using. If you are unsure, feel free to contact our support team.

Browser support for SNI

Since SNI is a relatively new technology, some older browsers do not support SNI. If your website uses a SSL on a shared IP address, and relies on SNI technology, all users will be able to view and interact with your website without any problem. However if they are using a older web browser, they may be presented with a SSL mismatch warning message first.

The following browsers support SNI technology:

  • Internet Explorer 7 and later
  • Firefox 2
  • Opera 8 with TLS 1.1 enabled
  • Google Chrome:
    Supported on Windows XP on Chrome 6 and later
    Supported on Vista and later by default
    OS X 10.5.7 in Chrome Version 5.0.342.0 and later
  • Safari 2.1 and later (requires OS X 10.5.6 and later or Windows Vista and later).
  • Note: No versions of Internet Explorer on Windows XP support SNI
  • Mobile Safari for iOS 4.0
  • Android 3.0 (Honeycomb) and later
  • Windows Phone 7
