Generate a random IPv6 address

random-ipv6-addr.py

#!/usr/bin/env python3
"""
Generate a random IPv6 address for a specified subnet
"""

from random import seed, getrandbits
from ipaddress import IPv6Network, IPv6Address

subnet = '2001:db8:100::/64'

seed()
network = IPv6Network(subnet)
address = IPv6Address(network.network_address + getrandbits(network.max_prefixlen - network.prefixlen))

print(address)

I needed to write it like this to get it to work:

subnet = u'2001:db8:100::/64'

Can you create it to make 1 random IPv6 address from multiple different IPv6 subnets?

It would be very useful if this is modified to give X amount of IPv6 IPs? for example it would generate 1000 IPv6 IPs starting from the lowest range. or does such script already exist?

$ for ip in {1..1000}; do python random-ipv6-addr.py ; done ? not exactly what you asked for but you can work from there..

Here's a way to generate them a bit faster

from random import getrandbits
from socket import inet_ntop, AF_INET6
from struct import pack

def random_ipv6():
    return inet_ntop(AF_INET6, pack('>QQ', getrandbits(64), getrandbits(64)))
    
for _ in range(400):
    print(random_ipv6())
