What NIPAP is

NIPAP is a free, open-source IP address management system designed for large address inventories. It provides a web interface and a feature-complete command-line tool, and can allocate the next available address automatically. Search supports IP prefix operators and regular expressions. NIPAP supports IPv6 with feature parity with IPv4 and is designed for native VRF support. It also offers subnet planning, integrated statistics, and audit history. Address data is stored and indexed in PostgreSQL using the ip4r module. The backend communicates through an XML-RPC API, and the project lists Python and Java client libraries. NIPAP is self-hosted and released under the MIT license at no cost. Debian and Debian derivatives are officially supported; other Unix-like systems may run it with manual dependency installation. Installation requires configuring authentication accounts for the backend and web interface. The maker describes user documentation as limited and directs users to GitHub issues for bugs, feature requests, and other issues.
