    Stop Google Chrome 'cycling' though internet ports?


    I've noticed Google Chrome 'cycles' through high-range internet ports while connected to the internet.

    To further explain: It opens a new port each time you open a new tab, and those new ports are usually sequentially one number higher than the last port opened.

    Is there a way to force Google Chrome to only use one port or to specify a restricted range of ports for it to cycle through?

    It needs to open ports for each site it like a phone if your talking on one line you need another line for a second call

    I was under the impression a single port could handle multiple transfers...

    A single port can handle multiple connections - that's how servers work. However, each connection must be uniquely identified.

    A TCP connection is defined by a set of: source address, source port, destination address, destination port.

    Let's say you are connecting to Windows 10 Help Forums, i.e. 184.172.52.107 port 80. That means the source address (your IP address), destination address (184.172.52.107), and destination port (80) are fixed. The only variable is the source port.

    If you want to make multiple simultaneous connections then you have to open up multiple ports. These ephemeral ports are dynamically assigned by the OS.

    So it can't syncopate data through a single port?

    What do you mean by "syncopate?"

    The number of ports used to connect to the same server depends on the protocol being used. For instance HTTP, depending on the version and configuration, may require a separate connection for every single request or it may allow multiple requests through a single connection - HTTP persistent connection - Wikipedia .

    If you're talking about using the same local port to talk to different servers, that's a different question. In theory this should be possible (similar to what is done on the server side) but I don't know the history of why sockets were implemented this way.
