Local Area Networks, Routers, and ARP - JuliaLightCNCS/Net-150 GitHub Wiki

Must be in the same local network to work. It communicates "NIC-to-NIC". The only thing that stops communication is the router.

All default gateways are routers but not all routers are default gateways.

Lookup tables in switches can also be called CAM Table or MAC Table.

ARP stands for Address Resolution Protocol and is only used for LAN.

ARP is layer 2 on the OSI scale.

ARP is used to resolve an IP address to a hardware address for final delivery of data packets to the destination.
