This DOS tool sends an ARP request using the packet driver API, waits for a reply, and then displays the result. Its primary purpose is to verify basic connectivity between your PC and other hosts on the local network.
Usage: ARPCHK <YOUR_IP> <TARGET_IP>
arpchk requires no TCP/IP configuration. It obtains its own MAC address directly from the packet driver and only needs to know which IP address you want to use as the source. You may specify any source IP as long as it belongs to your LAN and is not already in use by another device.
ARPCHK source code is tracked and versioned on its svn repository:
svn co svn://svn.mateusz.fr/arpchk
ARPCHK has been created by Mateusz Viste, who published it under the terms of the MIT license.
