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.

You are a network engineer responsible for creating the following network and testing it in your lab before your company implements it. There are four routers connected to each other via point-to-point serial links. Each router has a LAN attached to it with the specified number of hosts.

Use the Class C address of 192.168.241.0 and subnet it (using VLSM) in order to successfully implement the network requirements for the four sites

192.168.241.	Subnet Address	CIDR MASK	First Host	Last Host	Broadcast	# Hosts Needed	Location
192.168.241.							Chi - Nsh P to P
192.168.241.							Chi - Lvl P to P
192.168.241.							Chi - Mph P to P
192.168.241.							Mph Internal LAN
192.168.241.							Chi Internal LAN
192.168.241.							Nsh Internal LAN
192.168.241.							Lvl internal LAN
