How does ARP differentiate between requests and responses within the protocol?
- By checking the IP address
- By examining the hardware address
- By examining the operation code (OpCode) field
- By using a timestamp
ARP (Address Resolution Protocol) uses an OpCode field within the packet to distinguish between requests and responses. When an ARP packet has an OpCode of 1, it's a request, and when it's 2, it's a response. This allows devices to understand the purpose of the ARP packet.
