IP Address Management (IPAM)

Published Jul 11, 2026 · Updated Jul 11, 2026 · 2 min read

Keep an inventory of your IP space - customer, management and infrastructure subnets - with live utilization, so you always know how much address room is left. Add or import subnets and search any IP.

The IP Addresses page: subnet totals, usable/in-use counts and a table of subnets with type, VLAN and utilization

IPAM (IP Address Management) is ISPBox's inventory of your IP space - the subnets you route to customers, management and infrastructure - with live utilization so you can see how much address room you have left. It lives under IP Addresses in the sidebar and is part of the IPAM feature (a premium plan); it needs the network view permission.

1. The overview

The top of the page summarises your whole address estate: total subnets, usable addresses, how many are in use, and overall utilization. It is the fast answer to "are we about to run out of customer IPs?".


2. Subnets

The Subnets tab lists each subnet with its CIDR, name, location, type (Customer, Management, Infrastructure or Other), VLAN, gateway and a per-subnet utilization bar. Add one with Add Subnet - enter a CIDR between /16 and /30, a gateway, type and optional VLAN, and ISPBox validates it and checks for overlaps.


3. Import from router pools

Already have address pools configured on your routers? Import from router pools pulls them straight into IPAM so you do not have to re-type them - a quick way to seed your inventory from what is already deployed.


4. Searching for an address

The Search tab lets you look up a specific IP to see which subnet it belongs to and whether it is assigned - handy when troubleshooting or planning a new allocation.
