1. Convert an IP address given as 0xB3A74104 to the dotted decimal notation. What is the class of this address?

2. Consider a host whose address is 138.147.48.67/19

What is the network address?

How many addresses can be assigned to hosts in this network?

What is the first available address that can be assigned to a host?

What is the last available address that can be assigned to a host?

3. An organization is granted the block 135.34.212.0/22. The network administrator wants to create 32 subnets.

Find the subnet mask.

Find the number of addresses in each subnet.

Find the subnet address and the direct broadcast address for the 5th subnet.

Find the 9th address and the next to last address in the 31st subnet.

4. Give the mask in the dotted-decimal notation:

For a block of class A which results in 1024 subnets.

For a block of class B which results in 512 subnets.

Which combines 256 blocks of Class B into a supernet.

5. The network 127.154.24.0/21 is divided into 32 subnets. Can the following IP addresses be assigned to hosts? Explain your answers.

a. 127.154.24.0 b. 127.154.24.128 c. 127.154.25.120 d. 127.154.31.255 e. 127.154.30.250

6. A network of Class A has a subnet mask 255.224.0.0. What is the maximum number of hosts in each subnet?

7. Convert the decimal number 275820.0157470703125 to a base 256 number.
