Which statement about IP packets is true?

Which statement about IP packets is true?

• A. Each IP packet contains a destination address.
• B. IP packets contain no addresses.
• C. The destination address is optional in IPv6.
• D. The destination address is used only for ARP.

Answer: (A)

IP packets carry addressing in their headers so the network can deliver them to the right place. The destination address is included in every IP header, and routers use that address to forward the packet toward its final recipient. On the local link, a separate mechanism maps the destination IP to a hardware address (ARP in IPv4; Neighbor Discovery in IPv6) to get the packet to the next hop, but that step is about reaching the next device, not about overall delivery. So the statement that each IP packet contains a destination address is true, while the other options misstate how IP addressing and delivery work.
