Iterate over the IPv4 address space or CIDR in a random order

Question

I've been searching for this for a while, i didn't even found this question been asked before. So, i'm looking for a method to iterate over the IPv4 address space or CIDR in a nice random order without worrying of duplication. I've seen this implemented in Zmap

Answer 1

you could start use something like:

import random
r = random.randrange
ip = "{}.{}.{}.{}".format(r(0,255),r(0,255),r(0,255),r(0,255))

however you should still check if the IP is valid. ie filter 0.0.0.0 and so on
