[Windows] List all devices on the network in command prompt

arp -a


Notes:

What is ARP?

Address Resolution Protocol - which stores the mapping of IP address to physical MAC address.

What is dynamic type and static type?

Static type - you hard-coded the rule somewhere.

Dynamic type - the OS automatically find the rules for you when start-up.


Where does the table store?

ARP table stores in RAM in windows. So it clears and updates again after reboot.


Where does the static type rule store in windows?

Use netsh command in windows (remember to run as administrator) to figure it out yourself. ;)

Run netsh interface ipv4 reset  (remember to run as administrator).

:) Happy networking :D
