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.
FluxDHCP
FluxDHCP is a free, self-hosted DHCPv4 server managed through a web interface. It supports the DHCPv4 message types listed for RFC 2131, from discovery and address requests to acknowledgments, releases and other listed operations. Administrators can define address pools with subnet ranges, gateways, DNS servers, netmasks and lease times, choose sequential or random allocation, and check for overlapping pools. Static MAC-to-IP reservations and per-device DHCP option overrides are supported. Lease records track offered, bound, released and expired states, with automatic cleanup for expired entries. A packet logger records transaction details, direction, raw options, client information and millisecond timestamps. Webhooks can send DHCP events to external services by HTTP POST or GET, with template variables and custom headers. Configuration can be imported or exported as JSON, and imported changes are hot-reloaded. The project is AGPL-3.0 licensed and supports English and Chinese, dark mode and a responsive mobile-friendly interface. It requires Node.js 20 or later; Docker Compose is recommended, and binding UDP port 67 requires root or administrator privileges.
