Azure IPAM vs Obelinf

Azure IPAM helps Azure customers plan, deploy, manage, and monitor IP address space. It discovers networks, subnets, and endpoints across an Azure tenant, and can highlight orphaned endpoints and virtual network peers with misconfigurations. Users can group networks into Spaces and Blocks, monitor IP and CIDR consumption, and map external networks to Azure CIDR ranges. Planning tools show how many subnets of a chosen mask fit in a CIDR block. A REST API supports address-management automation for infrastructure-as-code and CI/CD workflows, with documented reservation paths through ARM and Bicep templates, Terraform, and CI/CD pipelines. The application runs as a container in Azure App Service or Azure Functions, or can be deployed API-only. Supporting infrastructure runs in the customer's Azure tenant, except for the public container registry. The open-source project is free; Azure infrastructure and hosting costs are separate. Deployment needs an Azure subscription and substantial tenant permissions.

Obelinf combines IP address management, device inventory, data center infrastructure management, network topology, rack management, cable tracking, VLAN/VRF management and infrastructure audit history. Its IPAM tools cover hierarchical subnets, VRF models, VLAN mapping, address status, reservations and live utilization. Interactive diagrams provide site-aware topology views and cable-path tracing; rack tools show elevations, U-position tracking, reservations and utilization across a fleet. A REST API and scoped, revocable keys support automation, while an MCP endpoint lets compatible assistants query and update records. The maker says create, update and delete actions are logged with user, timestamp, context and field-level changes. The free Personal plan allows up to 30 devices, four racks, five subnets, 100 IP addresses, 25 cables and 10 VLANs; VMs and clusters require a paid plan. Personal is free, Teams is $99 a month, and Scale is $299 a month. Paid plans have a 14-day trial that requires a credit card.
