ARP Ping Tool Description - Last Review: August 12, 2009

If you are looking for a way of finding all active IPv4 devices in a local network segment even if they are using device level firewalls (or personal firewalls), please see the ARP tool and look at the ARP scan function.

• Watch a demonstration of NetScanTools Pro doing an ARP Ping.

Capabilities:

• ARP Ping can ping an IPv4 address on your LAN with a broadcast MAC address ARP packet. If an ARP response packet is received from the device, the software continues to ping with a unicast ARP packet (unicast means a specific MAC address). Response time is shown for each responding ARP ping.
• ARP Ping can ping an IPv4 address on your LAN with a broadcast MAC address ARP packet and continue to ping the IP Address with a broadcast ARP packet. Response time is shown for each responding ARP ping.
• ARP Ping can search your LAN for duplicate IPv4 addresses using ARP packets sent to a specific IPv4 address. All responding MAC addresses are shown.

ARP is a protocol which associates an IPv4 address with a MAC (Media Access Control) address (xx-xx-xx-xx-xx-xx) over an ethernet network segment. ARP is normally not routed beyond a network segment. This tool uses WinPcap to generate ARP packets. See also the ARP tool for additional ARP tools including ARP cache control and ARP Sweep.

Important Notes:

• Since ARP packets are not routed (they will not go beyond your router), this tool cannot be used Ping a device across the internet. This tool requires the target IP address be on the same network segment or subnet as your computer is currently on.
• This tool cannot 'ping' a MAC address and get an IP address back in return -- the ARP protocol does not work that way.

Windows Vista compatibility: Fully functional as of v10.42.
