I. Conversion between binary and decimal forms of IP addresses

Convert the binary IP address into decimal form.

1. 10011010 . 00110010 . 00100000 . 00011111

2. 01100101 . 11001101 . 11011111 . 11100000
   Convert the IP addresses from decimal to binary form.

3. 64.27.101.17

4. 141.233.128.31

II. Determining Whether Two IP Addresses in Binary Form are on the Same Subnet

In each of the following exercises, you are to use the subnet mask to determine whether the two IP addresses belong to the same subnet or different subnets.

5.

01100110 . 10110010 . 00011100 . 00000001 IP Address 1

01100110 . 10100010 . 00011100 . 00000011 IP Address 2

11111111 . 11111100 . 00000000 . 00000000 Subnet Mask 1

6.

01100110 . 10100010 . 00011100 . 00000001 IP Address 1

01100110 . 10100010 . 00011101 . 00010011 IP Address 2

11111111 . 11111111 . 11110000 . 00000000 Subnet Mask 2

7.

11001000 . 01000100 . 10010100 . 10110100 IP Address 3

11001000 . 01000100 . 10011100 . 10101000 IP Address 4

11111111 . 11111111 . 11111111 . 11100000 Subnet Mask 3

III. Determining the appropriate subnet mask based on CIDR address

You have a ______ IP network ID. You wish to have _____ subnets. What should your subnet mask be if you wish to have the maximum possible number of hosts on each subnet ?

8. /21 ; 42

9. /27 ; 4

10. /16 ; 200

You have a ______ IP network ID. Your biggest network segment needs to have _____ hosts. What should your subnet mask be? How many different networks can you have given your answer?

11. /24 ; 100

12. /28 ; 12

13. /16 ; 50

IV. Finding the range of IP addresses for a subnet

For each of exercise, find the ranges of IP addresses for all subnets.

14. Network: 195.28.67.0/24 ; Subnet Mask: 255.255.255.128

15. Network: 141.176.128.0/17 ; Subnet Mask: 255.255.224.0
