VLAN conflict!

Last updated 4 months ago

The Problem

Spreadsheets don't scale

Duplicate entries. Stale data. No one knows who updated what, or when. Your network grows, but your tracking stays stuck in a shared Google Sheet that everyone's afraid to touch.

No collision detection for overlapping subnets
No audit trail when things change
No API for automation or CI/CD
No hierarchy — just rows and rows of flat data

Get Started

Three minutes to organized

No demo calls. No onboarding. Just sign up and start managing.

Create your workspace

Sign up with your email or Google account. Your tenant is provisioned instantly with row-level security.

Import or build

Upload your existing spreadsheet via CSV, or start fresh by adding subnets and folders from scratch.

Manage with confidence

Every change logged. Every conflict caught. Your network data is finally a source of truth, not anxiety.

API-First

Your network as an API

Most IPAM tools treat their API as an afterthought. Ours is a first-class citizen. Every action in the UI is an API call. Automate provisioning, sync with your CMDB, or build internal tools on top of your IP data.

Real-Time Events

Webhooks that keep everything in sync

Every change in your network fires an event. Subscribe to the ones you care about and IPCraft sends a signed HTTP POST to your endpoint within seconds. Sync your CMDB, trigger automation, or notify Slack when subnets change.

Event Types

EVENTsubnet.created

EVENTsubnet.updated

EVENTaddress.created

EVENTaddress.updated

EVENTvlan.created

EVENTvrf.created

Reliability

Exponential retry with 5 attempts

HMAC-SHA256 signature verification

Delivery log with response status
