SSL on your Website without a Dedicated IP Address

OVERVIEW

Our GRID and DV (Plesk) hosting services support the Server Name Indication (SNI) extension to the Transport Layer Security protocol. This makes it possible for Apache to use authentic SSL certificates for sites hosted on shared IP addresses. SNI helps to efficiently use IPv4 resources and provides the following benefits:

  • You can run any number of SSL sites with independent certificates on a single IPv4 address.
  • You can install independent SSL certificates on each of your sites. Now, there is no need to create another subscription. Each subscription can install an SSL certificate even if there is only one shared IP address on the whole server.

SUPPORTED BROWSERS

SSL support with SNI on shared IP addresses requires that the user's browser supports SNI. Most modern web browsers support it (e.g., IE 7 and above, Firefox, Opera, and Chrome). However, there are a few outlier exceptions:

  • Any Internet Explorer browser on Windows XP
  • Chrome 5 and older on Windows XP
  • Blackberry web browser
  • Windows Mobile phones up to version 6.5
  • Android mobile phone default browser on Android OS 2.x

Most of these exceptions are found when the end-user is running software that is incredibly out of date.

SNI ON THE GRID

SNI has been enabled on the Grid since September of 2013. This allows for multiple SSL certificates to be installed to a single Grid hosting service via each domain's Control Panel by Dytek's Staff.

ASP1 and Windows hosting

As of now (Feb 2018) SSL certificates on our Windows hosting platforms require a dedicated IP per website/SSL certificate.
