Consider the router and the three attached subnets below $($A$,$ B$,$ and C$).$ The number of hosts is

also shown below. The subnets share the $23$ high$-$order bits of the address space: $57\mathrm{.}210\mathrm{.}196\mathrm{.}0/23.$

Assign subnet addresses to each of the subnets $($A$,$ B$,$ and C$)$ so that the amount of address space

assigned is minimal, and at the same time leaving the largest possible contiguous address space

available for assignment if a new subnet were to be added. Answer the following questions. Show

all your calculations.

How many hosts can there be in this address space?

What is the subnet address of subnet A$?($CIDR notation$)$

What is the broadcast address of subnet $A?$

What is the starting address of subnet A$?$

What is the ending address of subnet $A?$

What is the subnet address of subnet B$?($CIDR notation$)$

What is the broadcast address of subnet $B?$

What is the starting address of subnet $B?$

What is the ending address of subnet B$?$

What is the subnet address of subnet C$?($CIDR notation$)$

What is the broadcast address of subnet $C?$

What is the starting address of subnet $C?$

What is the ending address of subnet $C?$
