 # How it works
 This attack continously sends spoofed ARP packets (using [scapy](https://github.com/secdev/scapy)) to every host on the network, poisoning its ARP table. </br>

 In case something goes wrong and the gateway ip cannot be automatically set, a custom one can be set by defining the `-g, --set-gateway` argument.
