Netdiscover

So, what is Netdiscover tool? What does this tool do? Netdiscover is not different from Wireshark or other kind of tools like that.
Netdiscover is acuatlly a pretty easy to use, and you do not need to configure anything….anything ๐Ÿ™‚
How does Netdiscorver work? it’s pretty simple. Netdiscover sends an ARP packages over the network, and by the devices answer, he know everything.
He know the MAC of the device, the IP of the device, and the moset important, the vendor of the device, which is a BIG advantage.
For example:
Netdiscover Q:”Who is 192.168.1.1?”
Some device A: “Hey…this is me, and my MAC is FF:ER:4E:FC:A3:1E, i am Cisco btw.”
Netdiscover Q:”Who is 192.168.1.2?”
Some device A: “Hey…this is me, and my MAC is FF:ER:4C:00:A2:2E, i am Edimax btw.”
Netdiscover Q:”Who is 192.168.1.3?”
Some device A: “Hey…this is me, and my MAC is F1:CR:2E:CC:A1:0E, i am Intel btw.”
And so on…and so on….
