Comprehensive IP Address Lists

This repository is a central, auto-updating source for IP address lists. The goal is to provide accurate, up-to-date IP lists for countries and online game servers, suitable for use in firewalls, routing tools, security research, and other network applications.

📂 Folder Structure

This project contains the following data:

  • ipv4-countries/: Contains IPv4 address lists, categorized by country.

  • ipv6-countries/: Contains IPv6 address lists, categorized by country.

  • game-servers/: Contains IP address lists for online game servers.

    • steam/: IP lists for servers of all games on the Steam platform.

⚙️ How It Works & Data Sources

This repository is automatically updated every 30 minutes by a GitHub Actions Workflow to ensure the data is always fresh and accurate.

1. Country IP Blocks

  • Source: Data for this section is sourced from the reputable herrbischoff/country-ip-blocks repository.

  • Format: Files are in .cidr format and categorized by their two-letter country code (e.g., US.cidr for the United States).

2. Steam Game Servers

  • Source: The server list is dynamically fetched directly from the Steam API.

  • Process:

    1. First, the complete list of all games on Steam is fetched via the GetAppList API.

    2. Then, for each game, the list of active servers is queried using the GetSDRConfig API.

    3. If active servers are found for a game, their IP addresses (both IPv4 and IPv6) are saved into a file named after the game (e.g., Counter-Strike_2.cidr).

💡 How to Use

You can use these lists in scripts, firewalls (like iptables or pfSense), or any other tool that requires traffic differentiation based on geolocation or a specific service.

For example, to block all IPs from a specific country using a Linux firewall:

# Example: Block all IPs from a hypothetical country (e.g., country code XX)
for ip in $(cat ipv4-countries/XX.cidr); do
  iptables -A INPUT -s "$ip" -j DROP
done
