Practical Issues in Networking - Assignment Example

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.

Begin by creating and assigning the LAN subnets you will use.  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 Table 1. 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 that 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.

For the WAN links, you have been assigned the 172.16.1.0/28 address space. Fill in the subnets in Table 2 by subnetting the assigned WAN space.

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