Title: Lab Exercise Four
Course: CNT 2001 Computer Networks & Communications > Section: Module 4 Network Addressing

Create a short essay (1 to 3 pages) in which you will present the design of a network for a small company.  The network will include private addresses for the LAN (which are not routable on the Internet) with a router that interconnects the LAN with an ISP’s (Internet Service Provider) regional network.  Your router will have a single public address on its’ ISP side and a single private address on its’ LAN side (the private address will be static).  Your router will provide NAT service to your LAN workstations, Internet bound traffic.

Your LAN will include 4 workstations and a few servers.  Your LAN will include a DHCP server that provides dynamically assigned addresses to the workstations in the LAN.  Your LAN will also include a database server.  The DHCP server and the database server will have static, private addresses.

Use the example of this network to

- Discuss what NAT is and how it works for your workstations.
- Compare static IP addressing with dynamic addressing.
- Explain how DHCP works.

Create a network diagram that shows what addresses are applied to which nodes (static or dynamic addresses, public or private addresses).  The network diagram can be produced using such tools as Visio from Microsoft Corporation, or Network Notepad (freely available from http://www.networknotepad.com/).

Include your references at the end of your essay.
