Last Updated on: 11th November 2024, 06:00 pm

1. Introduction to IP Geolocation

IP geolocation is the process of determining the real-world geographic location of an internet-connected device based on its IP address. This technology has numerous applications, from customizing content based on a user’s location to enhancing cybersecurity measures.

Every device connected to the internet is assigned an IP address, which serves as its digital identifier. IP geolocation leverages databases that map IP addresses to physical locations, providing information such as country, region, city, and even latitude and longitude coordinates.

2. The IP Geolocation Tool: An Overview

Our Python-based IP Geolocation Tool is designed to provide an interactive way to explore various aspects of IP geolocation. It offers features such as:

1. Finding your own public IP and location
2. Looking up the location of any IP address
3. Determining the IP and location of a given URL
4. Analyzing random IP addresses
5. Comparing locations of different URLs

This tool serves as both an educational resource and a practical utility, allowing users to gain insights into the geographic distribution of internet resources.

3. Setting Up Your Python Environment

Before we dive into the code, let’s ensure you have the necessary tools to run the IP Geolocation Tool. You’ll need:

1. Python 3.x installed on your computer
2. pip (Python package installer)
3. The following Python libraries:

• requests
• ip2geotools
• geopy

To install these libraries, open your command prompt or terminal and run:

pip install requests ip2geotools geopy

With your environment set up, you’re ready to explore the world of IP geolocation!

4. Breaking Down the Code

Let’s dissect our IP Geolocation Tool, explaining each component in detail.

Importing Necessary Libraries

import requests
from ip2geotools.databases.noncommercial import DbIpCity
from geopy.distance import distance
import socket
import random
import time

These lines import the required Python libraries:

• requests: This library allows us to make HTTP requests, which we’ll use to fetch our public IP address from an online service.
• ip2geotools: This provides access to IP geolocation databases. We’re specifically using the DbIpCity database for non-commercial use.
• geopy: This geographical processing library helps us calculate distances between coordinates.
• socket: This built-in Python library allows us to work with networking, including resolving domain names to IP addresses.
• random: We’ll use this to select random IPs and URLs for demonstration purposes.
• time: This allows us to add delays in our code, which is useful for avoiding overwhelming API services.

The IPGeolocation Class

class IPGeolocation:
    def __init__(self):
        self.blocked_countries = ["China", "Russia", "North Korea"]
        self.sample_ips = [
            '8.8.8.8', '1.1.1.1', '208.67.222.222', '9.9.9.9',
            '64.6.64.6', '84.200.69.80', '8.26.56.26', '208.67.220.220'
        ]
        self.sample_urls = [
            'www.google.com', 'www.amazon.com', 'www.facebook.com', 
            'www.twitter.com', 'www.github.com', 'www.stackoverflow.com'
        ]

This class encapsulates all the functionality of our tool. The __init__ method sets up:

• A list of countries to demonstrate IP blocking (purely for educational purposes)
• Sample IP addresses for demonstration (these are public DNS server IPs)
• Sample URLs for location comparison

Core Functionalities

Let’s explore the main methods of our IPGeolocation class:

Getting the Public IP

def get_public_ip(self):
    try:
        response = requests.get('https://api64.ipify.org?format=json', timeout=5)
        return response.json()['ip']
    except requests.RequestException:
        print("Failed to get public IP. Check your internet connection.")
        return None

This method fetches the user’s public IP address using the ipify API. It includes error handling to manage potential network issues:

• We use a try-except block to catch any RequestException that might occur.
• If successful, we parse the JSON response and return the IP address.
• If there’s an error, we print a message and return None.

Fetching Geolocation Data

def get_location(self, ip):
    try:
        response = DbIpCity.get(ip, api_key='free')
        return {
            "IP Address": response.ip_address,
            "City": response.city,
            "Region": response.region,
            "Country": response.country,
            "Latitude": response.latitude,
            "Longitude": response.longitude
        }
    except Exception as e:
        print(f"Failed to get location for IP {ip}: {str(e)}")
        return None

This method uses the ip2geotools library to fetch geolocation data for a given IP address:

• We use the DbIpCity.get() method with a free API key to retrieve location data.
• The response is packaged into a dictionary with key location details.
• If there’s an error, we print a message with the specific error and return None.

Calculating Distances

def calculate_distance(self, coord1, coord2):
    return distance(coord1, coord2).km

This simple method uses the geopy library to calculate the distance between two sets of coordinates in kilometers. This is useful for comparing the physical distance between different IP locations.

Resolving URLs to IP Addresses

def get_ip_from_url(self, url):
    try:
        return socket.gethostbyname(url)
    except socket.gaierror:
        print(f"Failed to get IP for URL {url}")
        return None

This method uses Python’s socket library to resolve a URL to its corresponding IP address:

• socket.gethostbyname() attempts to resolve the hostname to an IPv4 address.
• If it fails (e.g., due to a network error or invalid hostname), we catch the socket.gaierror exception, print an error message, and return None.

Checking for Blocked Countries

def is_country_blocked(self, ip):
    location = self.get_location(ip)
    return location and location['Country'] in self.blocked_countries

This method checks if an IP address belongs to a country in the predefined list of blocked countries:

• We first get the location of the IP address using our get_location() method.
• We then check if the country of this location is in our blocked_countries list.
• The method returns True if the country is blocked, False otherwise.

Analyzing Random IPs

def analyze_random_ips(self, count=5):
    print(f"\nAnalyzing {count} random IPs:")
    for _ in range(count):
        ip = random.choice(self.sample_ips)
        location = self.get_location(ip)
        if location:
            print(f"IP: {ip}, Location: {location['City']}, {location['Country']}")
            print(f"Blocked: {'Yes' if self.is_country_blocked(ip) else 'No'}")
        print()
        time.sleep(1)  # To avoid overwhelming the API

This method demonstrates how we can analyze multiple IP addresses:

• We loop count number of times (default is 5).
• In each iteration, we randomly select an IP from our sample list.
• We fetch and print the location of this IP, and check if it’s from a “blocked” country.
• We add a 1-second delay between requests to avoid overwhelming the API.

Comparing URL Locations

def compare_url_locations(self, count=3):
    print(f"\nComparing locations of {count} random URLs:")
    urls = random.sample(self.sample_urls, count)
    locations = []
    for url in urls:
        ip = self.get_ip_from_url(url)
        if ip:
            location = self.get_location(ip)
            if location:
                locations.append((url, location))
                print(f"URL: {url}, IP: {ip}, Location: {location['City']}, {location['Country']}")
        time.sleep(1)  # To avoid overwhelming the API

    if len(locations) > 1:
        print("\nDistances between URLs:")
        for i in range(len(locations)):
            for j in range(i+1, len(locations)):
                url1, loc1 = locations[i]
                url2, loc2 = locations[j]
                dist = self.calculate_distance((loc1['Latitude'], loc1['Longitude']), 
                                               (loc2['Latitude'], loc2['Longitude']))
                print(f"{url1} to {url2}: {dist:.2f} km")

This method demonstrates a more complex use case:

• We select random URLs from our sample list.
• For each URL, we resolve its IP address and fetch its location.
• We then calculate and print the distances between each pair of URLs.
• Again, we add delays to be respectful to the API service.

User Interface

def run(self):
    while True:
        print("\n--- IP Geolocation Tool ---")
        print("1. Get your public IP and location")
        print("2. Get location for a specific IP")
        print("3. Get IP and location for a URL")
        print("4. Analyze random IPs")
        print("5. Compare URL locations")
        print("6. Exit")

        choice = input("Enter your choice (1-6): ")

        # ... (code for each menu option)

        input("\nPress Enter to continue...")

This method provides a menu-driven interface for users to interact with the tool’s various features:

• It displays a menu of options in a loop, allowing the user to perform multiple operations.
• Based on the user’s choice, it calls the appropriate method to perform the desired operation.
• After each operation, it waits for the user to press Enter before showing the menu again.
