Python randomly generated IP address as string

If you just want a string:

import random

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

In [123]: '.'.join('%s'%random.randint(0, 255) for i in range(4))
Out[123]: '45.204.56.200'

In [124]: '.'.join('%s'%random.randint(0, 255) for i in range(4))
Out[124]: '7.112.222.205'

It may be too obvious but if you need random IPs within a range you can use this:

import random

for x in xrange(1,100):
  ip = "192.168."
  ip += ".".join(map(str, (random.randint(0, 255) 
                          for _ in range(2))))

  print ip

import faker
fake = Factory.create()
ip_addr = fake.ipv4(network=False)

lib has a lot of other useful options to fake data.

from faker import Faker  
faker = Faker()  
ip_addr = faker.ipv4()  

Reference: Fake-Apache-Log-Generator

An alternative way to generate a random string in the form of an IP address is:

>>> ip = '{}.{}.{}.{}'.format(*__import__('random').sample(range(0,255),4))
>>> ip
'45.162.105.102'

You also have Python’s ipaddress module available to you, useful more broadly for creating, manipulating and operating on IPv4 and IPv6 addresses and networks:

import ipaddress
import random

MAX_IPV4 = ipaddress.IPv4Address._ALL_ONES  # 2 ** 32 - 1
MAX_IPV6 = ipaddress.IPv6Address._ALL_ONES  # 2 ** 128 - 1


def random_ipv4():
    return  ipaddress.IPv4Address._string_from_ip_int(
        random.randint(0, MAX_IPV4)
    )

def random_ipv6():
    return ipaddress.IPv6Address._string_from_ip_int(
        random.randint(0, MAX_IPV6)
    )

Examples:

>>> random.seed(444)                                                                                                                                                                                                                                         
>>> random_ipv4()

Faster: Mimesis

If you’re looking for speed, try out Mimesis

from mimesis import Internet 
random_ip = Internet().ip_v4()

IP with valid CIDR: Faker

If you’re looking to generate a random IP adress with a valid CIDR, try out Faker

from faker import Faker  
random_valid_ip = Faker().ipv4()  

For more details on why Faker takes longer, see this issue.

from faker import Factory

fake_generator = Factory.create()
print(fake_generator.ipv4())

Be sure to pip install prior to trying to run the above!

pip install Faker

Check out the package documentation: https://faker.readthedocs.io/en/master/index.html

Here is a link directly to the ipv4 method docs

If trying to only generate private IP addresses based off user space (192.168.xxx.xxx, 172.16.xxx.xxx-172.31.255.255, and 10.xxx.xxx.xxx)

This post gives good answers

If you are trying to generate ANYTHING else, which can be considered public, use this (my code is based off the post above):

import random
def randomPublicIPaddress():
    '''
    oct 1 - cant be 10
    oct 2 - if oct1 == 192
                cant be 168
            if oct1 == 172
                cant be 16-31
    oct 3 - can be anything
    oct 4 - can be anything
    '''
    oct1 = random.choice([i for i in range(0,255) if i not in [10,127]])
    if oct1 == 192:
        oct2 = random.choice([i for i in range(0,255) if i not in [168]])
    elif oct1 == 172:
        oct2 = random.choice([i for i in range(0,255) if i not in range(16,31)])
    else:
        oct2 = random.randint(0,255)
    oct3 = random.randint(0,255)
    oct4 = random.randint(0,255)

    return ".".join(map(str,([oct1,oct2,oct3,oct4])))

Word of warning, there are many other ip address ranges that are considered "private" make sure to review the list on IANA
