OpenNetAdmin review
Broad, open-source DDI management for teams that want self-hosted control.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
OpenNetAdmin is an open-source IP address management system for organizations that want a self-hosted source of network information. Its scope covers IPv4 and IPv6 addressing, subnets, interfaces, hosts, MAC addresses, DNS records, DNS views, DHCP pools, and failover groups. A centralized AJAX web interface supports day-to-day administration, while the command-line interface supports scripting and batch maintenance. It is best suited to DDI administrators who want broad core coverage and the ability to customize the platform rather than purchase a hosted service.
The product’s strongest differentiator is breadth across core network data and configuration workflows. Administrators can manage DNS and DHCP data, generate configurations, maintain configuration archives, compare changes through diff views, and review subnet maps with utilization indicators. IPv6 support applies across subnets, interfaces, and DNS records, while the plugin framework provides an extension path for additional functionality. This makes OpenNetAdmin a practical fit for teams that need one system to organize authoritative network information and automate recurring maintenance.
The trade-off is operational ownership. With self-hosted deployment, the organization is responsible for running and maintaining the system, and the project repository notes that its last official version was several years earlier. The platform also does not provide AI features. Choose OpenNetAdmin when open-source control, scripting, configuration generation, and broad DDI coverage matter more than a managed deployment or newer project maturity signals. Consider an alternative when your priority is vendor-operated infrastructure, current commercial support structures, or built-in AI capabilities.
