Know what is on the networkbefore you touch it

LANWRX sweeps a subnet in seconds, identifies what it found and shows you why it thinks so, and tells you exactly what changed since last time. Built for the technician who has to explain the answer afterwards.

An example network. The last row reported nothing about itself, so LANWRX names no manufacturer and no model rather than guessing one.

Measured on a real 80-device network: 80 devices in 8 seconds, a /24 over Wi-Fi, without administrator rights.

addresses
254addresses

A /24 swept end to end. Give it a different range and it takes that instead — there is nothing to configure first.

seconds
8seconds

80 devices found and identified on a /24 over Wi-Fi, without administrator rights.

No driver, no packet capture, no elevation. It installs and runs as the user you are already signed in as.

inbound ports

Nothing listens. Licensing and updates are outbound HTTPS, so the machine you scan from is not a new way in.

The actual application

Scan, map, compare, report — in one window

This is a recording of LANWRX against a live network, not a mockup. Nothing in it was staged, re-timed or drawn afterwards.

Twenty seconds of LANWRX running against a live /24, recorded from the application itself. The sweep starts and the progress bar fills as ARP, ICMP, TCP and the discovery protocols answer; rows arrive as devices are found — 35 of them in 4.3 seconds, each carrying a manufacturer, a category, a latency and a confidence bar. The map view then draws the same devices as a tree hanging off the gateway. The changes screen offers to compare this visit against the last one. The report screen lists what is worth looking at: an FTP service left open on an access point, and two devices it could not identify — shown as unknown rather than guessed at.
  1. 0:00

    The sweep

    One button. The address range is already filled in from the adapter you are on.

  2. 0:07

    The map

    The same devices as a topology, hanging off the gateway — built from what answered, not from a diagram you drew.

  3. 0:13

    Changes

    This visit against the last one. Pick two scans of the same network and it tells you what moved, appeared and went quiet.

  4. 0:17

    The report

    What is worth looking at, what it could not identify, and the checks that did not run — said out loud rather than left blank.

One pass, seven protocols

Nothing waits for the slowest device

ARP, ICMP, TCP, mDNS, SSDP, WS-Discovery and NetBIOS run at the same time, and a result is rendered the moment it lands. You are reading the first two dozen devices while the rest of the range is still being probed.

The address that never answers costs you nothing: the sweep does not block on it, and the row for it never appears rather than sitting there greyed out pretending to mean something.

How the sweep works
The sweep on its own, in real time: 254 addresses on a /24, with results appearing as each device answers rather than all at once when the scan finishes.

From nothing to a document in four steps

There is no project to create, no agent to install and no inventory to seed first.

01

Point it at a network

It reads your adapter and offers the subnet you are on. Type a different one if you want. No configuration, no profile to build first.

02

Watch it fill in

ARP, ICMP, TCP, mDNS, SSDP, WS-Discovery and NetBIOS run together. Results appear as they arrive rather than after everything finishes.

03

Read the evidence

Open any device to see which probe said what. The identification is an argument you can check, not an answer you have to trust.

04

Leave something behind

Export CSV or JSON on the free tier. Pro produces a PDF with your details on it that a client can actually keep.

The rule the product is built on

LANWRX will tell you it does not know.

A scanner that always produces an answer is producing some answers it made up. That is fine until you put one in a document with your name on it.

So a model number appears only when the device reported that model itself. Anything inferred from a MAC prefix, an open port or a service banner is capped below “confirmed” and labelled with the evidence it came from. A randomised MAC is never attributed to a manufacturer. And when Find Device catches two disconnections at once, it names neither and shows you both.

How identification works
Confirmed

The device reported this model itself, over mDNS, SNMP or its own web interface.

High confidence

Several independent signals agree. Inference is capped at 85% no matter how many agree.

Likely

One signal, usually the MAC manufacturer plus an open port. Worth checking.

Unknown

It answered, and said nothing about itself. Shown as an address, with no invented name.

Pricing

The free tier is a real tool, not a demo

No trial clock, no device cap, no watermark across the results, no nag on launch. If you scan one network occasionally, LANWRX Free is the whole product for you and you never need to create an account.
