• The Branch 1 LAN will require 100 host IP addresses.
• The Branch 2 LAN will require 100 host IP addresses.
• The Branch 3 LAN will require 100 host IP addresses.
• The Branch 4 LAN will require 100 host IP addresses.
• The West LAN will require 400 hosts.
• The East LAN will require 400 hosts.
• The HQ LAN will require 500 host IP addresses.
• The links between each of the routers will require an IP address for each end of the link.

How many subnet are needed? 7 + 8 = 15
What is maximum number of IP address that are needed for a single subnet? 500 hosts
How many IP address are needed for each of the Branch LANs? 100 ip addresses
How many IP address that are needed for all of the connection between routers? 8 * 2 = 16 ip addresses
What is the total number of IP address that are needed? (100 * 4)+(400 * 2) + 500 + (2 * 8) = 1716 IP addresses

What will the subnet mask be for the subnetworks? 500 bulatkan keatas secara biner 512 = 2 pangkat 9. /32 - 9 = /23 or 255.255.252.0

How many usable host ip address are there per subnet? /32 - 23 = 9. 2 ^ 9 - 2 = 510 hosts

Filling in the following chart with the subnet information.

Subnet Number	Subnet Address	First Usable Host Address	Last Usable Host Address	Broadcast Address
