ARP Tool Description

The NetScanTools Pro ARP* Tool is a group of several tools you can use to view and modify your computer's network ARP cache. It's most useful feature is a tool for quickly scanning your subnet with ARP packets. ARP Tool capabilities and features:

Displays your ARP Cache. Shows all entries in the ARP cache. Cache contents can be filtered by Local or Remote Interface IP address. The manufacturer of each remote device's network interface is shown. The hostname for each IP address can be optionally shown.
ARP Cache Editing. Add a static entry to the ARP cache or delete any entry, static or dynamic from the ARP cache.
ARP Scanner (ARP Sweep). This is a very fast ARP scanner that shows every active IPv4 device on your subnet. This scanner shows all active devices even if they have personal firewalls or other built-in firewalls. Devices cannot hide from ARP packets like they can hide from Ping. To find active IP addresses outside your subnet, use the NetScanner tool (a Ping Sweep tool).

*ARP (Address Resolution Protocol) is a protocol used to associate an IP address with a MAC (Media Access Control) address (xx-xx-xx-xx-xx-xx) for communication over an ethernet network. See also ARP Ping.
