Proxifier Proxy

Download MarketApp, log in to your account and download the extension. Then go to the settings, find the item "Basic" and click on "Get your key". In the box provided to get your key, type Localhost, and then an IP key will appear, allowing you to trade freely on the marketplace.

To check if a port is available over UDP, you can try binding to the port for a short period. If the binding is successful, the port is available. If it fails, the port is already in use. Here's a simple example in Python:

import socket

def is_port_available(port, host='127.0.0.1', timeout=2):
    with socket.socket(socket.AF_INET, socket.SOCK_DGRAM) as sock:
        try:
            sock.bind((host, port))
            sock.settimeout(timeout)
            return True
        except OSError:
            return False
        finally:
            sock.close()

if __name__ == "__main__":
    port = 12345
    if is_port_available(port):
        print(f"Port {port} is available.")
    else:
        print(f"Port {port} is not available.")

In this example, the is_port_available function creates a UDP socket and attempts to bind to the specified port and host. If the binding is successful, the function returns True, indicating that the port is available. If the binding fails, the function returns False, indicating that the port is already in use.

Open the control panel of your computer, find and select the item "Network connection", and then click "Show network connections", "Local network connections" and "Properties". If there is a tick next to "Obtain an IP address automatically", then no dedicated proxy has been used. If you see numbers there, it will be your address.

Using the Internet in normal mode leads to loss of anonymity. In this case, the computer connects directly to the servers of sites and applications, recognizing the personal IP address and other confidential information. The use of redirecting proxy servers protects against all these unwanted consequences and allows you to bypass potential blocking. In order to take advantage of proxy servers of several types and varieties, it is necessary to install them properly.

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).
