OpenIPAM vs teemIP

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.

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.
