WhoIsConnectedSniffer
is a new utility 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.
