Q
Which are the features present in IPv4 but not in IPv6?
AA. Fragmentation
BB. Header checksum
CC. Options
DD. All of the mentioned
Correct Answer:
D. D. All of the mentioned
Explanation:
All the features are only present in IPv4 and not IPv6. IPv6 no longer has a header checksum to protect the IP header, meaning that when a packet header is corrupted by transmission errors, the packet is very likely to be delivered incorrectly.
