Every address, tied to the port that uses it
See aggregates and prefixes as one tree with a utilisation bar on every row, then drill down to the address, the interface and the DNS name.
IPv4 and IPv6 together
One tree, nested by CIDR within each VRF, filtered by family, VRF, site and status.
Find free space fast
The Free space tab lists the largest free blocks, each with Allocate and a Next available /N picker.
See it fill before it does
An exhaustion forecast shows days left per prefix, refreshed hourly.
From setup to answer in four steps
Import what you have
Bring in DNS and DHCP files and preview create, update and skip before anything is written.
Organise the space
Aggregates, prefixes, VRFs, VLAN groups, ASNs and FHRP groups each have their own register.
Allocate
Hand out prefixes, addresses, VLANs, VRFs and route targets against a service, contract line or plan.
Keep it honest
Reconcile adopts unmanaged addresses, flags conflicts and offers reclaim candidates for release.
What you can do
An IP map, one square per address
For subnets of up to 1,024 addresses each square is coloured Used, Free, DHCP, Reserved, Gateway, Conflict, Unmanaged or Reclaim candidate. Larger containers get a block map coloured by fullness.
DNS and DHCP records, kept in step
Saving an address with a DNS name offers to create or update the matching A, AAAA and PTR records. A consistency check finds missing and orphan PTRs, records outside IPAM and duplicates, with one-click fixes. DHCP groups scopes under their server, and a lease becomes a reservation in one step.
Allocate from templates
DDI templates preview the gateway, reserved ranges, DHCP scope and reverse zone a new prefix would get, and write nothing until you confirm.
Works with the rest of the platform
Network inventory and discovery
Walk from site to building, floor, room, rack and device. Compare what is documented with what discovery observed, and approve the differences before anything changes.

Patch by dragging between ports, let NetCosm route cables along your trays and work out the length, then trace any circuit end to end.
Read moreSecurity events (SIEM)
Logs arrive at your own endpoint and are matched to the device, asset or site they name. Router events are tied to the exact interface and link.
Read moreFrequently asked questions
Does it support IPv6?
Yes. IPv4 and IPv6 share the same tree, maps and tools.
How do we find free space?
The Free space tab lists the largest free blocks, with Allocate and next available /N.
Can we import from our current DNS and DHCP servers?
Yes, from exported files: BIND zone files, CSV exports from commercial DDI systems, and ISC, Kea and Windows DHCP exports. Each import is previewed before writing.
Does it keep DNS in step with IPAM?
It offers matching A, AAAA and PTR records when an address is saved, and a consistency check finds the gaps.
Will it warn us before a subnet fills up?
The dashboard shows an exhaustion forecast with days left against your threshold, refreshed hourly.
Does NetCosm run our DNS or DHCP?
No. It is the record of what your servers should hold.
NetCosm is hosted in the United Kingdom, so your rack, power and network records stay in the UK.
