Question
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

Explanation / Answer
For 115 Host Address on a network we have to reserve 7 bit reserve for the Host part.the subnet mask is 255.255.255.128 the dotted decimal notation is 11111111.11111111.1111111.10000000.
