WhoIsConnectedSniffer

WhoIsConnectedSniffer is a network analysis app that allows you to identify the devices connected to your network without needing to perform active scans. Unlike other apps that send packets to detect devices, WhoIsConnectedSniffer relies on passive packet capture, analyzing the traffic flowing through your network adapter to gather information about connected devices. This makes it less intrusive and reduces the possibility of alerting monitored devices. WhoIsConnectedSniffer requires Npcap to work correctly, as this tool is responsible for monitoring the network.

Protocols used for detection

To identify devices on the network, WhoIsConnectedSniffer uses various network protocols such as ARP, UDP, DHCP, mDNS, and BROWSER. By analyzing the packets associated with these protocols, this tool can detect a wide range of devices on the network and provide a detailed view of all the connected devices without generating additional traffic.

Detailed device information

Once WhoIsConnectedSniffer detects a device on the network, it will display relevant information, such as the IP address, MAC address, device name, description, operating system, network adapter manufacturer, and IPv6 address. The kinds of devices that WhoIsConnectedSniffer can detect include tablets, smartphones, computers, TVs, laptops, routers, security cameras, smart devices, and more. In short, WhoIsConnectedSniffer can detect practically any device no matter whether it's connected via Wi-Fi or Ethernet.

Export the collected data

WhoIsConnectedSniffer gives you the option to export a list of all the detected devices in different formats, including tab-delimited, comma-delimited, XML, and HTML files. This feature is especially useful if you need to document, analyze, or share the information collected on the devices connected to your network, as well as easily integrate it into other systems or reports.
