Refering to figure 1 below: You are the network administrator for the network depicted in the diagram.
You have been assigned the address space 10.1.16.0/21 to create the LANs you need, and the
172.16.1.0/28 space for your WAN links.
LAN: 10.1.16.0/21
WAN: 172.16.1.0/28
LAN Subnets
Begin by creating and assigning the LAN subnets you will use. In order to make the most efficient use of
your address space you should start by creating the subnet needed for the LAN with the most hosts and
then work you down to the smallest LAN.
Using the address space 10.1.16.0/21, create subnets for the LANs shown in the diagram and fill in the
table 1 below. Notice that the first 7 subnets are all basically the same size and all subnets are all factors
of 2 (remember 2n-2 where n is the number of host bits tells you the subnet size). Also remember for the
most efficient addressing you should use the smallest size subnet that provides you the needed number of
hosts.

Assign addresses
Use Table 3 below to document the IP addresses for the indicated interfaces following the guidelines
below:
1. Assign the first IP address for all LANs to the router interface.
2. Assign HQ the first IP address for all WAN links to Branch routers.
