NIPAP vs opAddress

NIPAP is a self-hosted IP address management system for large address inventories. It offers 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. IPv6 has feature parity with IPv4, and VRFs are supported natively. The system also includes subnet planning, integrated statistics, and audit history. Address data is stored and indexed in PostgreSQL with the ip4r module. The backend communicates through an XML-RPC API, and the project lists Python and Java client libraries. NIPAP is open source under the MIT license and is free. Debian and Debian derivatives are officially supported; the maker says other Unix-like systems may run it with manual dependency installation. Installation involves configuring authentication accounts for both the backend and web interface. The maker describes user documentation as rather limited and directs users to GitHub issues for bugs, feature requests, and other issues.
