Real$-$World Subnetting Practice Problems

Question $1$

You have been assigned the IP address space $192\mathrm{.}168\mathrm{.}1\mathrm{.}0/24$ for your network. You need to create $4$ subnets of equal size.

a$.$ What subnet mask should you use?

b$.$ What are the network addresses for each subnet?

Question $2$

Given the IP address $10\mathrm{.}0\mathrm{.}0\mathrm{.}0/8,$ you are required to create at least $500$ subnets.

a$.$ What is the new subnet mask?

b$.$ How many hosts can each subnet accommodate?

Question $3$

An organization has the network $172\mathrm{.}16\mathrm{.}0\mathrm{.}0/16.$ They need subnets that can each support up to $1000$ hosts.

a$.$ What is the appropriate subnet mask to use?

b$.$ How many such subnets can be created?

Question $4$

You have the IP address $192\mathrm{.}168\mathrm{.}10\mathrm{.}0$ and need to create subnets that can accommodate up to $30$ hosts each.

a$.$ What subnet mask should you use?

b$.$ List the first three subnet ranges, including network and broadcast addresses.
