Unfortunately, ARP is a stateless protocol. In the happy case, the one with the IP in the ARP request will reply us with his MAC address. To setup this mapping IP-MAC in the ARP table, we must first send ARP request as broadcast one to the LAN. In order for the packet to reach the destination, the destination IP address must be converted to the corresponding MAC address, so the transmission can be processed in the data link layer. When we want to send IP packet to another host (a computer in the same LAN, or the Gateway), we must know the destination IP address.
Netcut uses attacking technique called ARP Spoofing.ĪRP (Address Resolution Protocol) is a link layer procotol, it is used for resolving network layer address (IP) into link layer address (MAC).
Bad people can use Netcut to limit other 's internet access in same network How does Netcut work
