You have been given the $192\mathrm{.}168\mathrm{.}10\mathrm{.}0/24$ network address to subnet, with the following topology.

Determine the number of networks needed and then design an appropriate addressing scheme.

How many Subnets are there?

How many bits should you borrow to create the required number of subnets?

How many usable host addresses per subnet are in this addressing scheme?

Note: Usable host addresses $=2($n$)-2$ where n is the number of host bits left in the new subnet mask

What is the new subnet mask in dotted decimal format?

Dotted decimal

Binary

Original subnet mask $=255\mathrm{.}255\mathrm{.}255\mathrm{.}0$

$11111111111111111111111100000000$

New subnet mask $=255\mathrm{.}255\mathrm{.}255.?$

$111111111111111111111111????????$

What is the new CIDR notation for each new subnet? $($original network $=/24)$

What is the increment between subnets?

How many subnets are available for future use?
