1. Given the following host addresses, find the Subnet Address and the Broadcast Address that each host belongs to:

a)192.168.15.72 /24

Subnet Address:

Broadcast Address:

b)192.168.100.194 /26

Subnet Address:

Broadcast Address:

c)128.150.95.117 /27

Subnet Address:

Broadcast Address:

d)130.101.70.15 /22

Subnet Address:

Broadcast Address:

2.If you require 115 host addresses on a network, how many bits should you reserve for the host part of an IPv4 address?

What is the corresponding subnet mask? Give both CIDR and dotted decimal notations.
