  • And on the whole your ISP knows what you are doing. It’s not entirely true unless you are in specific countries where you have a government CA certificate installed in your browser.

    A normal ISP can see you are accessing bing or google, but don’t know what you are searching for. They can see you are accessing Netflix, but can’t see what show you are watching. VPN providers will likely see the same information.

    More concerning is your browser, it will know what show you are watching and what thing you searched for on Bing or Google.


















  • IP is the internet layer which is layer 2 and TCP is the transport layer which is layer 3.

    Why split physical and data link when they are so closely related? You can’t use vpi/vci on an ethernet port, you can’t use MAC addresses on a frame relay port. Bundle that shit together.

    Presentation, application, and session are all dealt with by the application anyway so why bother splitting them out from a network point of view?
