as can see of data has been decoded/interpreted rest isn't not sure why

can help?

you're printing raw udp packets, contain arbitrary binary data. of bytes in printable range, aren't in range converted �.

you can better @ data printing representation, shows printable bytes normal , shows unprintable ones hexadecimal escape codes. that, change print statement to:

    print repr(s.recv(2048)) 

i suspect you'd decode packets. that's quite possible, it's bit technical, , should study topic bit first. :) article silver moon, code network packet sniffer in python linux, looks quite helpful.
