Feature
VLAN & Subnet Management
Organize network segmentation with VLANs, VRFs, and subnets.
Segmentation
VLANs, VRFs, and subnets, together.
VLAN tracking
See which VLANs exist at each site and which devices are tagged, so IDs are never a mystery.
VRF isolation
Model virtual routing tables with route distinguishers, keeping tenants and environments separate.
Connected and visible
All of it stays linked in one view, so segmentation never turns into silos.

Subnet Allocation
Allocate from the parent block, without waste.
Hierarchical allocation
Carve subnets out of parent blocks while keeping the whole tree visible.
Utilization at every level
See which subnets are assigned, available, or running out of space.
Plan before you need it
Allocate ahead of time instead of racing to find space at deploy time.

Utilization Monitoring
Never run out without warning.
Assigned, reserved, available
Every address has a clear state, so the picture is never fuzzy.
Spot exhaustion early
Watch consumption climb and act before conflicts become incidents.
One source of truth
No more cross-referencing documents to answer a simple question.
