Lecture-6

On what date did the Internet Assigned Numbers Authority (IANA) announce the allocation of its last IPv4 addresses?

• • A. January 1, 2011

• • B. February 3, 2011

• • C. March 15, 2011

• • D. December 31, 2011

Which of the following is NOT a reason for transitioning from IPv4 to IPv6?

• • A. Exhausted public IP addresses

• • B. Improper packet header design

• • C. Dependency on ARP causing broadcast storms

• • D. Lack of support for hierarchical address allocation

What is one key advantage of IPv6 over IPv4?

• • A. Dependency on ARP

• • B. Smaller routing tables

• • C. Nearly infinite address space

• • D. Complex packet header

How long is an IPv6 address?

• 32 bits

• 64 bits

• 96 bits

• 128 bits

Which feature of IPv6 improves the performance of mobile networks?

• • A. Simplified packet header

• • B. Plug-and-play

• • C. Mobility support

• • D. Hierarchical address allocation

What does the Flow Label field in the IPv6 header help with?

• • A. Error checking

• • B. Differentiating real-time traffic

• • C. Encrypting packet data

• • D. Extending address length

Which field in an IPv6 header is similar to the Time to Live field in an IPv4 packet?

• Version

• Traffic class

• Hop Limit

• Next Header

What type of addresses does IPv6 use to ensure the uniqueness and scalability of addresses?

• • A. Broadcast addresses

• • B. Hierarchical addresses

• • C. Multicast addresses

• • D. Anycast addresses

1. How does IPv6 handle the Options field differently from IPv4?

• IPv6 places the Options field in extension headers.

• IPv6 includes the Options field in the basic header.

• IPv6 removes the Options field entirely.

• IPv6 limits the Options field to 20 bytes.

What is the purpose of the Traffic Class field in the IPv6 header?

• To indicate the version of IP

• To specify the length of the packet

• To identify the next header type

• To manage packet priority for QoS
