Luminati Proxy

It means organizing a connection through several VPN-servers at once. It is used to protect confidential data as much as possible or to hide one's real IP address. This principle of connection is used, for example, in the TOR-browser. That is, when all traffic is sent immediately through a chain of proxy servers.

To disable WebRTC in Chrome using Selenium ChromeDriver in C#, you can use ChromeOptions to set the necessary command-line arguments. Here's an example:

using OpenQA.Selenium;
using OpenQA.Selenium.Chrome;

class Program
{
    static void Main()
    {
        ChromeOptions chromeOptions = new ChromeOptions();

        // Disable WebRTC
        chromeOptions.AddArgument("--disable-webrtc");

        // Other options (customize as needed)
        // chromeOptions.AddArgument("--use-fake-device-for-media-stream");
        // chromeOptions.AddArgument("--use-fake-ui-for-media-stream");

        IWebDriver driver = new ChromeDriver(chromeOptions);

        // Your Selenium script...

        driver.Quit();
    }
}

In this example:

--disable-webrtc is added as a command-line argument to disable WebRTC in Chrome.

Additional options related to WebRTC are provided in comments. Uncomment and customize them based on your specific requirements.

Make sure to replace the "Your Selenium script..." comment with the actual logic of your Selenium script.

You can check it with the ping command from the command line in Windows. It is enough to enter it, with a space - the data of the proxy server (including the number of the port used) and press Enter. The reply message will tell you whether or not you have received a reply from the remote server. If not, the proxy is unavailable, respectively.

A proxy server spoofs the IP address, port, and hardware information. It can also act as a secure gateway for data transmission in an already encrypted form (for example, this is how a proxy with the SOCKS5 protocol works).

The easiest option is to use ready-made online proxy checkers. For example, Hidemy.name, which shows the type of protocol used. Or you can simply run Speedtest - this will show you the bandwidth and response speed (ping).
