Python randomly generated IP address as string

>>> import random
>>> import socket
>>> import struct
>>> socket.inet_ntoa(struct.pack('>I', random.randint(1, 0xffffffff)))
'197.38.59.143'
>>> socket.inet_ntoa(struct.pack('>I', random.randint(1, 0xffffffff)))
'228.237.175.64'

NOTE This could generate IPs like 0.0.0.0, 255.255.255.255.

If you just want a string:

import random

ip = ".".join(map(str, (random.randint(0, 255) 
                        for _ in range(4))))
