Review IPv4 & IPv6

What is the main reason for the creation of IPv6 addressing?

• To reduce the size of IP addresses

• To enhance security

• To improve network speed

• To increase the number of available addresses

How many bits does an IPv6 address consist of?

• 64 bits

• 128 bits

• 32 bits

• 16 bits

What is the purpose of using hexadecimal values to represent IPv6 addresses?

• To increase security

• To improve network performance

• To reduce the number of characters in the address

• To simplify routing tables

How many groups are there in an IPv6 address, and how many bits are in each group?

• 10 groups of 64 bits each

• 4 groups of 32 bits each

• 8 groups of 16 bits each

• 6 groups of 8 bits each

What is the purpose of using double colons in IPv6 address compression?

• To replace groups of 0s

• To separate different address components

• To indicate a network prefix

• To specify a unique address

Which of these addresses is the shortest abbreviation for the IP address: 3FFE:1044:0000:00AB:0003:0000:0000:0057?

• 3FFE:1044:0:AB:3::57

What is the host portion for the host address 2001:DB8:12:BC15:A::1/64?

• ::1

• BC15:A::1

• 12:BC15:A::1

• A::1

If an IPv6 address /48 network prefix is assigned with an additional 16-bits (4-hexadecimal bits) used as a subnet range, how many subnets can be assigned? 

• 8,192

• 32,678

• 65,536

• 16,384

What is the primary purpose of an IPv4 address?

• To identify a device on a network

• To encrypt data packets

• To provide a backup for IPv6

• To manage network traffic

Which of the following is a valid IPv4 address?
