DacatDHCP vs teemIP

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.

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.
