DomainMapper is a Python-based tool designed to resolve popular web service domain names into IP addresses. It's targeted at network administrators and users who need to map services like Netflix, Google, or Discord to their corresponding IP ranges for network management, firewall configuration, or custom routing. The tool offers flexible output formats and robust IP aggregation capabilities.

How It Works

DomainMapper queries multiple DNS servers for each domain, ensuring comprehensive IP address discovery rather than stopping at the first response. It intelligently filters out duplicate IPs, self-referential IPs, and common placeholders like 0.0.0.0. The tool supports aggregating discovered IP addresses into common subnet masks such as /24 and /16, with an option for a combined /24 + /32 mode, facilitating efficient network rule creation.
