FluxDHCP vs Jen Kea DHCP Management Console

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.

Jen Kea DHCP Management Console is a free, GPL v3 web interface for managing ISC Kea DHCP Server. Operators can manage leases, reservations, subnets, and infrastructure from a browser, while the dashboard shows subnet utilization, lease activity, server status, HA state, and alerts. Lease tools include filtering active leases, releasing them, cleaning stale leases, converting dynamic leases to reservations, and CSV import or export. Subnet and pool edits are applied over SSH after Kea validation, a host-side backup, multi-server preflight, and rollback protection. Optional IPv6 support covers leases, devices, reservations, subnet pools, timers, and metrics. Alert channels include Pushover, Telegram, Slack, ntfy, Discord, email, and generic webhooks; optional plugins add network discovery, IPAM Lite, local DNS synchronization, and other functions. Jen connects through the Control Agent or direct daemon sockets, uses MySQL or MariaDB for Kea data, and uses SSH for configuration and service operations. The recommended guided installer runs on Ubuntu 22.04 or 24.04, and Docker deployment is also supported. The project targets homelab-to-small-business operators managing a handful of servers, not large fleets.
