Solution for Subnetting Exercise #1

Assume that you have been assigned the 132.45.0.0/16 network block.

You need to establish eight subnets. 

1 Three binary digits are required to define the eight subnets. 

2 Specify the extended network prefix that allows the creation of eight

subnets.

/19 or 255.255.224.0 

3 Express the subnets in binary format and dotted decimal notation:

Subnet #0: 10000100.00101101. 000 00000.00000000 = 132.45.0.0/19

Subnet #1: 10000100.00101101. 001 00000.00000000 = 132.45.32.0/19

Subnet #2: 10000100.00101101. 010 00000.00000000 = 132.45.64.0/19

Subnet #3: 10000100.00101101. 011 00000.00000000 = 132.45.96.0/19

Subnet #4: 10000100.00101101. 100 00000.00000000 = 132.45.128.0/19

Subnet #5: 10000100.00101101. 101 00000.00000000 = 132.45.160.0/19

Subnet #6: 10000100.00101101. 110 00000.00000000 = 132.45.192.0/19

Subnet #7: 10000100.00101101. 111 00000.00000000 = 132.45.224.0/19

4 List the range of host addresses that can be assigned to Subnet #3

(132.45.96.0/19).

Subnet #3: 10000100.00101101.011 00000.00000000 = 132.45.96.0/19

Host #1: 10000100.00101101.011 00000.00000001 = 132.45.96.1/19

Host #2: 10000100.00101101.011 00000.00000010 = 132.45.96.2/19

Host #3: 10000100.00101101.011 00000.00000011 = 132.45.96.3/19

:

Host #8190: 10000100.00101101.011 11111.11111110 = 132.45.127.254/19 

5 What is the broadcast address for Subnet #3 (132.45.96.0/19)?

10000100.00101101.011 11111.11111111 = 132.45.127.255/19
