In-Depth Information
Most operating systems will display the ARP table with the arp -a command.
To turn a dynamic ARP entry for your router into a static entry in Windows,
open a Command Prompt as Administrator and type in the following command,
but replace [Router IP] and [Router MAC] with the IP and MAC address of
your router:
C:\> netsh -c "interface ipv4" add neighbors "Wireless Network
Connection" "[Router IP]" "[Router MAC]"
The Wireless Network Connection argument might need to be adjusted to
match the name of your interface. For wired connections, the common name is
Local Area Connection .
The equivalent command for Mac OS X or Linux is:
$ sudo arp -s [Router IP] [Router MAC]
Setting a static ARP entry for the router in Windows
To verify that your static ARP entries mitigate the ARP poisoning attacks, start an
Ettercap session and use the chk_poison plugin.
