Study Notes
Address Resolution Protocol (ARP)
- The primary function of ARP is to resolve the MAC address of a device from its known IPv4 address.
Network Stack Layers
- The MAC address is associated with the Data Link Layer (Layer 2) of the network stack.
IPv6 and MAC Addresses
- IPv6 uses the Neighbor Discovery Protocol (NDP) to associate the IPv6 address with the MAC address.
ARP Usage
- A device uses ARP when it wants to send a packet to another device on the same network, but it only knows the IPv4 address of the destination device.
Layer 3 Logical Address
- The function of the Layer 3 logical address (the IP address) is to identify devices at the network layer and facilitate routing between networks.
