What do you mean by loopback interface? An organization is assigned the block 2000:1456:2474/48. What is the IPv6 address of an interface in the third subnet if the IEEE physical address of the computer is (F5-A9-23-14-7A-D2)₁₆?

You are given the following network address and subnet mask:

Network address: 192.168.10.0

Subnet mask: 255.255.255.252

i) How many subnets?

ii) How many hosts?

iii) What are the valid subnets

iv) Fill in the table below

Define subnetting. An organization is assigned the block 172.30.0.0/16. It wants to create 256 subnets.

i) Find the subnet mask

ii) Find the number of addresses in each subnet

iii) Find the first and last addresses in subnet 10

iv) Find the first and last addresses in subnet 256

Derive the routing table for the following Fig. 1. Can router R1 in Fig. 1 receive a packet with destination address 140.24.7.194? What will happen to the packet if this occurs?

Show abbreviations for the following IPv6 addresses:

i) 1234:0000:3456:0000:A058:0000:0000:F02F

ii) 0000:0001:0000:0000:0000:56E2:24.120.12.90

 What are the differences between IPv4 and IPv6 addressing?

Briefly define sub-netting and super-netting. How do the subnet mask ad super-net mask differ from a default mask in classful addressing?

What is the difference between a pubiic IP and a private IP? Provide examples of each.

The following shows the IPv6 datagram format. Compare it with IPv4 datagram format.
