How do I determine the client IP type in Python - IPv4 or IPv6

We can determine IPv6 and IPv4 based on its separator character. IPv4 uses period(.) and IPv6 uses colon(:).

Below code shows how to determine the client protocol

import socket
def get_client_protocol():
    # Get the client's IP address
    client_ip = socket.getaddrinfo(socket.gethostname(), None)[-1][-1][0]
    # Check if it's an IPv6 address
    if ':' in client_ip:
        return "IPv6"
    # Check if it's an IPv4 address
    elif '.' in client_ip:
        return "IPv4"
    else:
        return "Unknown IP address type"
# Test the function
print("Client is using", get_client_protocol())

 In this Python code:

1. We import the socket module.
2. We use socket.getaddrinfo() to get the IP address associated with the hostname of the local machine. We then extract the IP address from the result.
3. We check if the IP address contains a colon (:), which indicates an IPv6 address, or a dot (.), which indicates an IPv4 address. If neither is found, it's considered an unknown IP address type.

You can run this code to determine whether the client is using IPv4, IPv6, or an unknown IP address type.
