Learn How the Address Resolution Protocol (ARP) Works in 10 Minutes

In this video I do a quick overview of the address resolution protocol, commonly known as ARP. I explain why MAC addresses are needed when communicating on a local network and how ARP helps populate mac address tables on networked-devices.

Thank you very much for this explanation, keep going.

Nice explanation, but there is no "G" in Hex numbers, like in the MAC address of the bottom PC.

[@plaintextpackets]

LOL

Have you used Cisco packet tracer? It's a great teaching tool to see step by step which packets go where in a network

[@plaintextpackets]

I did years ago when I first started my career

[@TheLazyJAK]

​@@plaintextpacketsyeah I haven't used it since college, but your hand drawn network reminded me of it lol. Might be good to show people what's actually going on, but might not be worth all the setup

Is it correct to say that ARP broadcasting is use to get L2 address and ip broadcast is use to get L3 addr

[@plaintextpackets]

ARP L2 broadcast used to map layer 2 (MAC) to layer 3 (IP). Layer 3 broadcasts are mainly used for application purposes (eg MDNS)
