ARP Scan Tool Description - Ping your LAN
with ARP Packets and See What Responds.
The ARP Scan tool can send ARP packets to every
IPv4 address on your subnet and show responding devices even if
protected by a firewall. This tool is part of NetScanTools Pro
and is also called MAC scan.
About the ARP Scan Tool
The ARP Scan
Tool (also called ARP Sweep or MAC Scanner) is
a very fast ARP packet scanner that shows every active
IPv4 device on your subnet. Since ARP is
non-routable, this type of scanner only works on
the local LAN (local subnet or network segment).
The ARP Scan Tool shows all
active devices even if they have firewalls. Devices cannot hide
from ARP packets like they can hide from Ping. To
find active IP addresses outside your subnet, use
the Ping Scan Tool
(a Ping Sweep tool AKA NetScanner).

Version 11 ARP Scan Tool Slideshow
packets are not routable (the packets will not go beyond
your router), so this tool is limited to target IPv4 addresses on the
same network segment or subnet as your computer
is currently on.
sends ARP packets to every IP address in the
range you specify.
Purpose of this tool
- This tool discovers all active devices in a
IPv4 range (usually a subnet) even if protected by
software designed to hide the presence of the device
- personal firewalls, operating system firewalls or
other stealth programs. If you are using IPv4
ethernet or WIFI, the devices on your LAN must
respond to ARP or they cannot communicate.
Sends ARP Packets to every IPv4
address specified and looks for the mandatory ARP Reply.
You are limited to scanning IP addresses in your subnet
- why? Because ARP is not routed. IPv4 connected devices
cannot hide from ARP - the must respond if they are to
be communicating using IPv4 ethernet.
Displays Responding ARP Replies. Shows
all devices responding with an ARP reply message during the scan. The manufacturer
of each remote device's network interface is shown.
The hostname for each IP address can be optionally shown.

addresses over the range scanned with ARP Packets.
What is ARP?
ARP (Address Resolution Protocol) 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
to generate ARP packets. See also the
ARP Cache tool for ARP cache
manipulation and the ARP
Ping tool for testing a single device on your LAN.
