Description

LAN Detector (LAND) is a web application for exploring the intranet environment. It scans your private network and searches for active IP addresses on the detected subnet.
Being just a web page in a browser, LAND does not require you to install or run any application or extension on your computer.

Usage

Simply navigate to LAN Detector using your browser and wait a few minutes for your intranet to be scanned and private IP addresses detected.

In the case if your local network is not detected (or you know the subnet address and want to save a couple of minutes), enter the subnet address in the edit box and click "Use subnet" button:

Troubleshooting

• The browser must not be anonymous (e.g. Tor Browser). It must also support modern scripting features (so Internet Explorer won't work either).
• The application is designed to detect IP addresses in small (home) networks (the most common Class C, /24 subnets). So, if your computer is on multiple Class C networks, the application may try to detect IP devices in the wrong subnet (for example, in a docker swarm or in another virtual subnet that you may have). If it doesn't detect anything, just refresh the LAND webpage and another subnet will be selected for scanning.
• Depending on your local environment, the application may not work properly (it may detect either too many IP addresses, or none at all). For example, it can't detect anything from Firefox on one of my Android devices, although it works well in Chrome on the same device.

Privacy

In short, your private IP addresses remain private. The server is not provided with the information that can be used for deducing yours private IP addresses. The information about detected local IP addresses does not leave your computer and remains in the browser local storage. Although the detection history is displayed when navigating the  LAND web page, you can delete it from your browser any time (simply delete the Site Data for land.etaras.com).
