WhoIsConnectedSniffer - Network discovery tool that listens to network packets on your network

WhoIsConnectedSniffer is a network discovery tool that listens to network packets on your network adapter using a capture driver (WinpCap or MS network monitor) and accumulates a list of computer and devices currently connected to your network. WhoIsConnectedSniffer uses various protocols to detect the computers connected to your network, including ARP, UDP, DHCP, mDNS, and BROWSER.

For every detected computer or device, the following information is displayed: (Some of the fields might be empty if the information cannot be found inside the packets) IP Address, MAC Address, name of the device/computer, description, Operating System, Network Adapter Company, IPv6 Address.

After collecting the connected computers/devices information, you can easily export the list to tab-delimited/comma-delimited/xml/html file.

Protocols supported by WhoIsConnectedSniffer

• ARP:WhoIsConnectedSniffer listens to this protocol to get the IP address and MAC address of computers and devices.
• UDP:When a computer broadcasts a UDP packet to all other computers, WhoIsConnectedSniffer extracts from it the IP address and the MAC address.
• DHCP:When a computer connects to the network, it usually sends a DHCP request. WhoIsConnectedSniffer uses this request to get the host name and IP address of the computer.
• mDNS:This protocol is used on Linux and Mac OS systems. WhoIsConnectedSniffer uses it to get the host name and IP address of the computer, and also the operating system (on Linux)
• BROWSER:This protocol is mainly used by Windows, but some Linux systems supports this protocol too. WhoIsConnectedSniffer uses it to get the name of the computer, description text of the computer, and the operating system.
