2^k   = (1251 + 6).

2¹¹ = (2048>1257).

Network’s bits = 32 – 11 = 21

Network’s IP-Addresses = 192.168.0.0/21Broadcast’s IP-Addresses: - 192.168.7.255Subnet masks = 255.255.248.0Range of IP addresses = 192.168.0.1- 192.168.7.254

Second branch

The second branch has Business College and the staffs and administration building and each has a number of required ip addresses as follows Business College 106 and staff/administration College 265 and below is the total ip address required in each as follows.

Total Hosts are 371 therefore,

Total Hosts = 371

2^k   = (371 + 4).

2⁹ = (512>375).

Network’s bits = 32 – 9 = 23

Network’s IP-Addresses = 192.169.0.0/23

Broadcast’s IP-Addresses: - 192.169.1.255

Subnet masks = 255.255.254.0

Range of IP addresses = 192.169.0.1- 192.169.1.254 [5].
