FusionLayer Infinity review
A hybrid, multitenant IPAM suite for complex networks and cloud environments.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
FusionLayer Infinity is a software-defined IP address management solution for telecom operators, service providers, enterprises, and complex hybrid infrastructures. It centralizes network blocks, subnets, prefixes, IP addresses, VLANs, VRFs, policies, DNS, and DHCP-related data. The product supports IPv4, IPv6, and dual-stack networks, with multitenancy for environments that require overlapping networks and VRFs. It is best suited to organizations managing shared, distributed, or hybrid infrastructure rather than teams seeking a lightweight subnet register.
Infinity’s integration and automation scope is a central strength. Its REST API supports orchestration and cloud integrations, while compatibility spans AWS, Azure, VMware, OpenStack, Hyper-V, Nutanix, Red Hat, Microsoft, F5, Cisco, SDN controllers, and network orchestrators. DNS and DHCP management integration, network and port discovery, inventory views, custom fields, and automated hostname generation extend the system beyond basic address allocation. These capabilities make it a strong fit for operators that need a network source of truth across cloud, virtualization, SDN, and on-premises environments.
Control and governance features add value for larger or shared environments. Role-based access control, self-service allocation, audit trails, changelogs, and undo functionality support delegated administration and change visibility. Infinity is offered as a self-hosted product with API access, and a 30-day trial is available. Its commercial model requires contacting sales, and there is no free plan. Organizations that need multitenancy, dual-stack planning, discovery, and orchestration integrations should shortlist Infinity; teams with straightforward IP tracking needs may prefer a narrower tool with a simpler commercial and operational model.
