On-premises
your address plan stays with you
Your IP address plan, always up to date — subnets, addresses, VLANs and VRFs, filled in by your DHCP server and network monitoring instead of a spreadsheet.
Planning, discovery, conflicts and an API for automation — in one clean web interface.
Nest subnets in supernets and carve free space visually — split evenly, by host count or block by block — then create them in one go with names, VLANs and gateways.
Every subnet as a map of its addresses: used, DHCP lease, reserved, gateway and free at a glance. Click a free square to record it.
Ping sweeps find the hosts nobody wrote down and propose the subnets they live in — for a person to confirm.
Our DHCP server reports scopes, leases and reservations; Atlas One reports what it scans and sees in ARP tables. Your own edits always win.
Duplicate addresses, overlapping subnets, addresses that fit no subnet and stale entries are listed for clean-up.
Reserve the next free address atomically, read subnets and export to Jupiter or your own tools with scoped API tokens.
The same address in different routing tables, VLANs per site and every subnet tied to where it lives.
Customers or departments see only their own space. Viewer, operator and administrator roles, Active Directory sign-in and two-factor authentication.
Bring your spreadsheet in as CSV, take everything out as CSV, and download a full backup at any time.
Pick a supernet, say how many subnets or hosts you need, and Meridian draws the plan to scale. Click a block to halve it, join two back, tick the ones to create.
The address map shows which addresses are used, leased, reserved or free — and the next free one is a click away.
Every plan has every feature — you choose by how many IP addresses Meridian manages.
Every plan starts with the one-month free trial — no payment details. Quotes and invoices by email; there is no online payment. Prices per installation and year, excluding VAT. Shown in your currency at the European Central Bank reference rate of 2026-10-26 — approximate; your quote states the final amount.
Meridian runs on your own Rocky Linux or Red Hat Enterprise Linux 9 server with PostgreSQL. Install the package, open it in a browser, and the one-month trial starts when you activate it.
