Here's a simple way to compare lists of IP addresses in python You might for example want to compare a baseline inventory list to a routine Nessus scan to ensure all machines are logged in the inventory

Code:

import difflib


#edit the path


ips1 = "/Users/your_user/Github/sub_folder/compare-lists/input/file1.txt"
ips2 = "/Users/your_user/Github/sub_folder/compare-lists/input/file2.txt"


ips1_lines = open(ips1, 'r').readlines()
ips2_lines = open(ips2, 'r').readlines()


difference = difflib.HtmlDiff().make_file(ips1_lines,ips2_lines,'IP Set 1','IP Set 2')
difference_report = open('difference_report.html', 'w')
difference_report.write(difference)
difference_report.close()

How to Use:

Create your 2 text files with the IP Addresses in a list

  • One IP address per line
  • Store files in 'input' directory

    Edit the file paths to the IP Address List Files

ips1 = "/Users/your_user/Github/sub_folder/compare-lists/input/file1.txt"

ips2 = "/Users/your_user/Github/sub_folder/compare-lists/input/file2.txt"

Note: The ip addresses used in this repo were created with ipvoid.com/random-ip

Run

python3 compare-lists.py

Sample Output:
