Possible to identify which interface connected via socket configuration?

Possible to identify which interface connected via socket configuration? I have an ESP32 which happens to have both WiFi and Ethernet (via W5500) support. I am opening a socket with '0.0.0.0' as the target address. But this seems to have a side effect that since I am listening to all interfaces, both WiFi and Ethernet, I don't see an obvious way to determine which interface the client used to connect to the ESP32. is there a way to programmatically determine this? Below the code I am using to open socket, accept connection.

        # Use 0.0.0.0 For All Interfaces...
        theAddress = getaddrinfo('0.0.0.0', 80)[0][-1]
        theSocket = socket()
        if (theSocket is None):
            raise Exception('No Socket?')
        theSocket.setsockopt(SOL_SOCKET, SO_REUSEADDR, 1)
        theSocket.bind(theAddress)
        theSocket.listen(1)
        theAddress, thePort = theAddress
        print(f"Socket Open {theAddress} Port {thePort}")
        theClient = None
        while True:
            try:
                theClient, theAddress = theSocket.accept()
                if (theClient is None):
                    raise Exception('No Client?')
                theAddress, thePort = theAddress
                print(f"Client Connect {theAddress} Port {thePort}")

Opening two sockets, running them on different threads, or cores, etc. seems overly complex, just to know which IP address the client happen to connect to.

Hello
If you use async mode ?
Look at the userver.py example from Peter in v3/as_drivers/client_server ... For me it's ok for different class of ip

Thanks for the suggestion... I have not as yet looked at async approach. But I did find away to figure out the interface, or IP Address at least, by parsing the request string, parsing out the 'host' value. Not perfect but at least functional to as which interface was used.
