Information

Partition an existing Subnet into clean, contiguous IP ranges for distinct device tiers.

Gateway Protection

The planner verifies if standard Gateway assignments (like `.1` or `.254`) visually collide with a requested sequential block array, dynamically hopping over the reserved Gateway IP to prevent address conflicts.

Intra-Subnet Only

This limits planning to the bounds of a single Network and Broadcast ID. If you need to chop an enterprise super-block into multiple VLANs, use the VLAN Planner tool instead.

How the IP Address Planner Works

The IP Address Generator allows infrastructure engineers to logically slice up a single broadcast domain (Subnet) into cleanly grouped, non-overlapping IP assignments based on intended device roles.

Rather than relying on disjointed spreadsheets to track which `.10` to `.50` addresses belong to the server farm, you can input your constraints into the IPam Calculator above. The engine automatically maps the capacity boundaries, reserves your predefined gateway addressing, and yields start/end targets for every single device tier on your network.

Example Usage: Standard Office Deployment

Scenario: Provisioning a /24 Office VLAN

You are provisioning a standard `10.0.8.0/24` network (VLAN 8) for a corporate branch office. You need to assign IP blocks for internal IT hardware, static devices, and a robust DHCP scope for wireless guests, ensuring the `.1` Gateway isn't accidentally swallowed by a dynamic pool.

  • Infrastructure (10 IPs):10.0.8.2 - 10.0.8.11
  • Servers (30 IPs):10.0.8.12 - 10.0.8.41
  • Printers (15 IPs):10.0.8.42 - 10.0.8.56
  • DHCP Scope (150 IPs):10.0.8.57 - 10.0.8.206

Frequently Asked Questions

How does this differ from the VLAN subnet planner?

The VLAN planner sits a layer above this tool. It splits a massive network (e.g. `10.0.0.0/16`) into smaller chunks (like `/24` or `/23`). This tool operates **strictly within** those smaller chunks, assigning linear ranges of host IPs.

Why did the block start numbers shift unexpectedly?

Our generator engine natively protects the Gateway IP. If a linearly assigned block touches your defined gateway (e.g. `.254`), the engine will automatically split or hop the range starting point past the boundary to prevent an immediate addressing conflict on layer 3.
