Prefixloom
Plan IPv4 CIDR blocks, project growth, preserve reservations, compare utilization pressure, and document ownership without an enterprise IPAM.
Focused field tools
Keep prefix, network, broadcast, gateway, DHCP, and reservation intent explicit.
Model realistic device, tenant, service, and failure-domain growth.
Preserve infrastructure, anycast, virtual IP, and operational headroom.
Compare every proposed block inside its routing and VRF context.
Keep layer-two identifiers separate from layer-three addressing.
Account for provider-reserved addresses and subnet-specific constraints.
Prefixloom performs deterministic IPv4 capacity planning from recorded inputs; it does not discover live devices, reserve addresses, configure routers, or replace authoritative IPAM. Verify overlap, routing, DHCP, VRFs, security zones, cloud reservations, and current assignments before deployment.
