Q1: Based on the information in the graphic shown, design a network
addressing scheme that will supply the minimum number of hosts per
subnet, and allow enough extra subnets and hosts for 70% growth in all
areas without using VLSM. Circle each subnet on the graphic and answer
the questions below.

(Round up to the next whole number)
Total number of subnets needed =
Number of host addresses in the largest subnet group

Total number of address needed for the largest subnet =
Start with the first subnet and arrange your
sub-networks from the largest group to the smallest:
Subnet 1: IP address range for Dallas
Subnet 2: IP address range for Ft. Worth
Subnet 3: IP address range for Router A to Router B serial
connection
Subnet 4: IP address range for Router A to Router C serial
connection
Subnet 5: IP address range for Router C to Router D serial

Q3: Repeat Question 1 while using VLSM on the subnet between Router C-
Router D in order to provide IP addresses for the 3 WAN connections
between routers. Then, calculate the amount of IP addresses that were
freed by this operation.
