ARP
(Address Resolution Protocol)
The Address Resolution Protocol (ARP) is a communication protocol used to map IP addresses to physical MAC addresses on a local network. ARP is essential for enabling devices to communicate within the same network segment.
When a device needs to send data to another device, it uses ARP to discover the MAC address associated with the destination IP address. This process is critical for the functioning of Ethernet networks. However, ARP is also vulnerable to attacks like ARP spoofing, which can lead to security breaches. Implementing measures like static ARP entries and network monitoring can help mitigate these risks.
