2 / 14 IP & Addressing

ARP

A host wants to send a packet to another host on the same local network. It knows the destination IP but not the MAC address. How does it resolve this?

A

The MAC address is embedded in the IP header by the sender's OS

B

It sends the packet to the default gateway which looks up the MAC address

C

It broadcasts a request asking 'who has this IP?' and the owner replies with its MAC address

D

It queries the DNS server for the MAC address
