Article Summary:

●  Understand IP address structure and reserved ranges

●  Build working Python scripts for IPv4/IPv6 generation

●  Learn to filter out invalid/reserved IP addresses

●  Discover why raw IP generation isn’t enough for anonymity

●  Implement practical proxy rotation with Thordata

What Is an IP Address and How Does It Work?

An IP (Internet Protocol) address is a unique numerical identifier assigned to every device connected to a network. It serves two primary functions:

1. Network Identification: Identifies your device on the internet or local network

2. Location Addressing: Provides information about your geographical location

IPv4 vs. IPv6: Key Differences

IPv4 Address Format:

●  Structure: Four octets separated by periods (e.g., 168.1.1)

●  Range: 0.0.0.0 to 255.255.255.255

●  Capacity: ~4.3 billion addresses

IPv6 Address Format:

●  Structure: Eight hexadecimal groups separated by colons (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334)

●  Capacity: 340 undecillion addresses

●  Solution to IPv4 exhaustion

Why Generate Random IP Addresses? Practical Use Cases

Legitimate Applications:

●  Software Testing: Simulate traffic from diverse geographic locations

●  Network Security: Test firewall rules and intrusion detection systems

●  Web Scraping: Avoid detection by rotating request origins

●  Load Testing: Simulate multiple users from different IP ranges

What You Cannot Do:

❌ Assign generated IPs directly to your machine

❌ Bypass geographic restrictions without proxies

❌ Hide your real identity without intermediary services

How to Generate Valid Random IP Addresses in Python

Understanding Reserved IP Ranges

Before generating IPs, exclude these reserved blocks:

Address Block Address Range Description
0.0.0.0/8 0.0.0.0 – 0.255.255.255 Current (local, “this”) network
10.0.0.0/8 10.0.0.0 – 10.255.255.255 Used for local communications within a private network
100.64.0.0/10 100.64.0.0 – 100.127.255.255 Shared address space for service provider and subscriber communication with carrier-grade NAT
127.0.0.0/8 127.0.0.0 – 127.255.255.255 Used for loopback addresses to the local host
169.254.0.0/16 169.254.0.0 – 169.254.255.255 Used for link-local addresses when no IP is specified (e.g., DHCP failure)
172.16.0.0/12 172.16.0.0 – 172.31.255.255 Used for local communications within a private network
192.0.0.0/24 192.0.0.0 – 192.0.0.255 IETF Protocol Assignments, DS-Lite (/29)
192.0.2.0/24 192.0.2.0 – 192.0.2.255 Assigned as TEST-NET-1, for documentation and examples
192.88.99.0/24 192.88.99.0 – 192.88.99.255 Reserved. Formerly used for IPv6 to IPv4 relay
192.168.0.0/16 192.168.0.0 – 192.168.255.255 Used for local communications within a private network
198.18.0.0/15 198.18.0.0 – 198.19.255.255 Used for benchmark testing of inter-network communications between separate subnets
198.51.100.0/24 198.51.100.0 – 198.51.100.255 Assigned as TEST-NET-2, for documentation and examples
203.0.113.0/24 203.0.113.0 – 203.0.113.255 Assigned as TEST-NET-3, for documentation and examples
224.0.0.0/4 224.0.0.0 – 239.255.255.255 In use for multicast (former Class D network)
233.252.0.0/24 233.252.0.0 – 233.252.0.255 Assigned as MCAST-TEST-NET, for documentation and examples (part of multicast space)
240.0.0.0/4 240.0.0.0 – 255.255.255.254 Reserved for future use (former Class E network)
255.255.255.255/32 255.255.255.255 Reserved for the “limited broadcast” destination address

Complete Python Implementation

import random

import ipaddress

def generate_random_ipv4():

    “””

    Generate a random, non-reserved IPv4 address

    Returns a string in the format X.X.X.X

    “””

    while True:

        # Generate a random IP address with four octets

        ip = f”{random.randint(0, 255)}.{random.randint(0, 255)}.{random.randint(0, 255)}.{random.randint(0, 255)}”

        

        # Check if the generated IP is within the reserved blocks

        if not ipaddress.IPv4Address(ip).is_reserved:

            return ip

# Test the function

if __name__ == “__main__”:

    ip = generate_random_ipv4()

    print(f”Generated IP: {ip}”)

Why Generated IPs Alone Won’t Protect Your Privacy

The Fundamental Limitation

While you can generate random IP addresses, you cannot directly use them for outgoing connections. Your internet traffic always routes through your ISP-assigned IP.

Real Solutions for Anonymity:

Proxy Servers: Intermediate servers that mask your real IP, and Residential Proxies: Legitimate IPs from real devices.

Implementing Practical IP Rotation with Proxies

Python Proxy Rotation Script

import requests

import random

# Pool of proxies

proxies = [

    “<PROXY_URL_1>”,

    “<PROXY_URL_2>”,

    “<PROXY_URL_3>”

]

# Get a random proxy config

def get_random_proxy():

    return {“http”: random.choice(proxies), “https”: random.choice(proxies)}

# Example usage

proxy = get_random_proxy()

response = requests.get(“https://example.com”, proxies=proxy)

Frequently asked questions

How does a random IP address generator work in Python?

38

The generator creates valid IP addresses by producing random numbers within the 0-255 range for each octet, then validates them against IANA’s reserved ranges using Python’s ipaddress module to ensure they’re usable for public traffic

Can I use generated IP addresses for actual web browsing?

No, generated IPs are only simulated addresses. To actually route traffic through different IPs, you need proxy servers.

What’s the difference between datacenter and residential proxies for IP rotation?

Datacenter proxies come from cloud servers and are cheaper but easier to detect. Residential proxies like Thordata’s come from real ISP-assigned IPs, making them more legitimate and harder to block for scraping tasks.
