Most VPN Services are Terrible

Most VPN Services are Terrible

Short version: I strongly do not recommend using any of these providers. You are, of course, free to use whatever you like. My TL;DR advice: Roll your own and use Algo or Streisand. For messaging & voice, use Signal. For increased anonymity, use Tor for desktop (though recognize that doing so may actually put you at greater risk), and Onion Browser for mobile.

A simple python script converts a Classless Inter-Domain Routing (CIDR)-formatted IP address into an IP range and netmask.
#!/usr/bin/env python
# python subnet.py 200.100.33.65/26
import sys
# Get address string and CIDR string from command line
(addrString, cidrString) = sys.argv[1].split('/')
# Split address into octets and turn CIDR into int
addr = addrString.split('.')
