Address Resolution Protocol: ARP packet structure and demonstration

How does Address Resolution Protocol work? In this video Druvis examines ARP examples and breaks them down byte by byte, and we learn how to mitigate ARP poisoning attacks.

0:00 ARP fundamentals
3:10 ARP packet dissected
3:57 ARP in action
5:27 hex examined
6:49 gratuitious ARP
8:21 ARP spoofing
8:58 static entries

Great explanation of ARP!
Thanks for the video!

Great and thoroughly explnation of how ARP works!
ARP is a protocol that just because it work, is overlooked by many.

Nice intro to ARP, example how to limit the number of MAC addresses on a given port will be great.

Hi Druvis, thank´s a lot, great video! 😀👍 Maybe a Part 2 with more deeper tips? (e.g. Bridge-Filter and how to use them...)

What MikroTik is missing for ARP protection is Dynamic ARP Inspection (DAI).

Awaiting for next part of video. How to protect my network from spoofing.

@mikrotik, whrere is the long awaited EIN (NAT) video? Nobody kows exactly what EIN does compared to the regular NAT...

Could you please tell me which is the Operation system of the laptop? Thank you in advance :)

I wonder if maybe ARP table is my issue when MikroTik router is restarted (electricity cut off) after which I want to use Wake-Up-Lan to turn on PC because then this function doesn't work unless I manually turn on my PC and then shut down so like at that moment Mikrotik router's ARP table is updated and then I can start using WoL magic packets which turn on my PC. Should I add like static ARP table?

Proxy arp is by default on routers? That doesn't sound right at all. RouterOS, its enabled by default. I'd like to know what you meant by that.

Una buena noticia Manu para los amantes de la familia Poco de Xiaomi. Yo voy feliz con mi PocoF5 PRO, una verdadera bestia como dices tú, pero ¿me convendrá cambiar el próximo año a PocoF6 PRO? Un abrazo a la distancia para ti Manu😊.
