In their own words
DacatDHCP
DacatDHCP combines an IPv4 DHCP service with a web interface for configuring address pools, viewing leases, and monitoring status. The lightweight single-file application bundles the service and management interface. Settings include network-interface selection, address ranges, gateway, DNS, and lease duration. The interface shows assigned addresses and client information, while version 1.0.0 adds fixed MAC-to-IP mappings with matching logs. The main release supports Windows 10, Windows 11, and Windows Server 2016 or later on Windows amd64. Management works in Edge, Chrome, and other modern Chromium-based browsers; Internet Explorer 11 is not supported. The interface listens on 127.0.0.1, and write endpoints use CSRF and origin checks. Administrator privileges are required. DacatDHCP is permanently free and open source under Apache License 2.0. It is intended for labs, test environments, temporary LANs, small networks, troubleshooting, and isolated networks. Address pools must share the selected interface’s subnet. Leases remain in memory after startup and are not restored after restart; active IP-conflict detection is not provided.
OpenIPAM
OpenIPAM is a free, open-source IP address management and CMDB tool for network and infrastructure inventory. It manages CIDR subnets, IP assignments and reservations, duplicate-IP conflicts, VLANs, IP ranges, and subnet calculations. DHCP tracking covers scopes, leases, reservations, options, and utilization. Its inventory supports 14 host types, hardware lifecycle tracking, locations and racks, maintenance windows, and company records. It can run in a browser with local storage or use an optional Python Flask backend with server-side SQLite for multi-user access. Server mode adds SAML 2.0 single sign-on with Microsoft Entra ID, authenticated routes, and a REST API for entity management, cross-entity search, dashboard statistics, and JSON backup or import. The project describes signed session cookies with an eight-hour lifetime and user-attributed audit entries. CSV host import and JSON backup and restore, including DHCP data, are supported. Browser-mode data stays in the browser; server-mode data is stored in the server-side SQLite file. The plan costs nothing. Current browser support covers Chrome, Firefox, Safari, and Edge, with WebAssembly and ES6+ required.
