ArpSpyX - ARP Packet Sniffer

ArpSpyX is an ARP packet sniffer that displays a list of IP and MAC addresses found by analyzing ARP traffic on your network. It can be used to easily gather MAC addresses of network machines remotely, quickly identify new clients on your wireless network, and identify ARP poisoning attacks by tracking multiple MAC addresses for a single IP address.

It supports active scanning method that sends ARP who-has requests to every IP address on the network of the specified device. It can sort the list box by IP or MAC address. It dynamically determines the available network adapters (which are no longer hard coded based on common device names). There is the ability to export IP and MAC address list to a text file.
