NIPAP
NIPAP is a self-hosted IP address management system for handling large address inventories.
What NIPAP is
NIPAP is a self-hosted IP address management system for handling 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 includes subnet planning, integrated statistics, and audit history. Address data is stored and indexed in PostgreSQL with the ip4r module. The backend exposes an XML-RPC API, and the project lists Python and Java client libraries. NIPAP is free, open-source software under the MIT license. Debian and Debian derivatives are officially supported; other Unix-like systems may run it with manual dependency installation. Installation includes setting up authentication accounts for the backend and web interface. The maker describes its user documentation as limited and points users to GitHub issues for bugs, feature requests, and other concerns.
Good
- Automatically allocates the next available address.
- Search supports IP prefix operators and regular expressions.
- IPv6 has feature parity with IPv4.
- Includes subnet planning, statistics, and audit history.
- Free and MIT-licensed.
Watch out
- Official support is limited to Debian and Debian derivatives.
- Other Unix-like systems may need manual dependency installation.
- User documentation is described as limited.
Who it suits
NIPAP is aimed at network engineers managing substantial address inventories, including IPv6 and VRFs. It suits teams able to self-host and configure authentication for its backend and web interface.
Verdict
NIPAP combines address allocation and search with IPv6, VRF, and subnet-planning support. Its self-hosted deployment and limited documentation are worth considering before setup.
