Kubernesis DDI vs OpenIPAM

Kubernesis DDI provides managed DHCP, DNS, and IP address management across headquarters, branches, cloud, and remote sites. One console handles scopes, ranges, exclusions, reservations, and options for IPv4 and IPv6. New leases automatically create matching address and DNS records, while expired leases are released. Critical scopes can run on server pairs that continue issuing and renewing leases after one server fails, and large branches can use local DHCP during WAN outages. A REST API creates scopes and reservations in provisioning workflows. Lease history retains MAC address, hostname, and device type associations; unknown devices can be flagged, and lease records can be forwarded to a SIEM. Deployment supports high-availability appliances or virtual installations across on-premises and cloud environments. Kubernesis can import Windows DHCP or ISC DHCP configurations and perform staged cutovers with rollback. Integrations include identity providers, SIEMs, service-management tools, cloud platforms, hypervisors, and network vendors. Operations are covered by an agreed SLA with engineers in Gurugram, India. Pricing is on request.

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.
