Question 5

What do you mean by IP datagram fragmentation?

Marks: 5

Year: 2022 Final TU

1. Definition IP datagram fragmentation is the process of breaking a large IP packet (datagram) into smaller fragments so that it can pass through a network with a smaller Maximum Transmission Unit (M

Question 6

Explain in detail about the structure of IPv6 address. Differentiate between IPv4 and IPv6 address.

Marks: 5

Year: 2022 Final TU

1. IPv6 Address Definition: IPv6 (Internet Protocol version 6) is the next-generation IP addressing scheme designed to overcome IPv4 limitations, primarily address exhaustion. - Uses 128-bit addre
