Figure 981. Virtual hosting Slide presentation

  • One physical host system

  • Serving multiple sites e.g.:

    • https://www.foo.org

    • https://www.second.org


Figure 982. Implementing virtual hosting Slide presentation

  1. Port based virtual hosting

  2. IP based virtual hosting

  3. Name based virtual hosting

    Typically using Server Name Indication (SNI)

Figure 984. IP based, pros / cons Slide presentation

  • Host system: One IP per site to serve

  • Pro: TLS handshake without SNI.

    Supporting older clients.

  • Downside:

    • IP address waste

    • Host system NIC configuration required

Figure 986. Name based, pros / cons Slide presentation

  • Host system: Common IP address

  • Pro

    • No IP address waste

    • No Host system NIC configuration required

  • Cons: Excluding older non SNI supporting clients.

    (Internet Explorer on Windows XP, Android below V. 2.3)

  • SNI allows for eavesdropping requested site's name.
