Question $5$

Given the IP address $203\mathrm{.}0\mathrm{.}113\mathrm{.}0/24,$ you need to divide it into $5$ subnets.

a$.$ What subnet mask would you use?

b$.$ Is it possible to create exactly $5$ subnets? Explain your reasoning.

Question $6$

For the network $10\mathrm{.}10\mathrm{.}0\mathrm{.}0/16,$ design a subnetting scheme that allows for at least $200$ hosts per subnet and at least $100$ subnets.

a$.$ What subnet mask will you use?

b$.$ How many hosts per subnet will this allow?

Question $7$

Given the IP address $192\mathrm{.}168\mathrm{.}100\mathrm{.}0$ with the subnet mask $255\mathrm{.}255\mathrm{.}255\mathrm{.}192$:

a$.$ How many subnets are available?

b$.$ How many usable hosts per subnet are there?

Question $8$

An ISP has allocated you a block of IP addresses starting with $198\mathrm{.}51\mathrm{.}100\mathrm{.}0/24.$ You need to create subnets for networks that require different numbers of hosts:

One subnet with $100$ hosts

Two subnets with $50$ hosts each

Four subnets with $25$ hosts each

a$.$ Propose a subnetting scheme to accommodate these requirements.

b$.$ Provide the network and broadcast addresses for each subnet.
