Python UDP IPv6 client & server

udp_ipv6_client.py

import socket

UDP_IP = "::1"  # localhost
UDP_PORT = 5005
MESSAGE = "Hello, World!"

print "UDP target IP:", UDP_IP
print "UDP target port:", UDP_PORT
print "message:", MESSAGE

sock = socket.socket(socket.AF_INET6, # Internet
					socket.SOCK_DGRAM) # UDP
sock.sendto(MESSAGE, (UDP_IP, UDP_PORT))

udp_ipv6_server.py

import socket
  
UDP_IP = "::" # = 0.0.0.0 u IPv4
UDP_PORT = 5005

sock = socket.socket(socket.AF_INET6, # Internet
						socket.SOCK_DGRAM) # UDP
sock.bind((UDP_IP, UDP_PORT))

while True:
	data, addr = sock.recvfrom(1024) # buffer size is 1024 bytes
	print "received message:", data
