FluxDHCP vs teemIP

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.

teemIP is an open-source IP address management solution for mapping, planning, and auditing an organization’s address plan. It manages IPv4 and IPv6 with DNS, DHCP, and NAT, and connects addresses to configuration items such as devices, services, sites, DNS records, reservations, and change requests. Teams can inspect subnet details in a hierarchical IP tree and handle address requests through tickets with assignment, tracking, and history. Role-based access control and logging support traceability for changes. A documented REST API and connectors integrate it with tools including iTop, GLPI, Jira, Centreon, Zabbix, Nagios, Lansweeper, AD/LDAP, VMware, Proxmox, Grafana, and Power BI. teemIP can be hosted on-premises or on sovereign cloud providers. The maker positions it as an inventory and network-mapping aid for NIS2 compliance. Community is free; Standard costs €500 a year, billed annually, with an annual commitment. Advanced active DNS/DHCP, high availability, and DNS security needs require scope validation.
