Use the techniques demonstrated in class to create subnets from the network addresses and topologies provided.

For each subnet provide the Network Address, Host address range, and the Broadcast address.

Hints:

End points

require an IP address on their network port.

Routers

are layer $3$ devices and require an IP address on EVERY PORT

Switches

are layer $2$ devices and DO NOT require IP addresses.

Network #$1$:

Network Address: $192.\mathrm{.}168\mathrm{.}15\mathrm{.}0/24($Subnet Mask: $255\mathrm{.}255\mathrm{.}255\mathrm{.}0)$

How many subnets are required?

How many additional bits must be "borrowed" from the last octet to create the subnets?

What is the subnet mask for the subnets?

How many usable hosts does this create per subnet?

Remember: usable hosts $=2^n-2,$ where $n=$ the number of zeroes in the subnet mask.

Fill in the table for each subnet:
