Subnetting Example: ABC Packaging
Objective:
To use your subnet knowledge to design an IP addressing scheme for the ABC
Packaging.
Tools and Materials:
Paper and pencil
Background:
(from Part 1) You are working as the network administrator for ABC Packaging. You
are to design a network that focuses upon scalability and adaptability. There are five
departments: Administration (14 people, 5 printers), Engineering (22 people, 5 printers, 1
file server), Production (5 people), Accounting (11 people, 4 printers, 1 database and file
server), and Sales/Marketing (11 people, 4 printers, 1 file server). Each department will
require a separate subnet. The servers will have their own subnet. Be sure to connect
them to the Internet with a T-1 line. You task is to design an IP addressing scheme that
will address all current needs as well as future expandability. If you see anything that
may want to address feel free to note it. Scalability, adaptability, reliability and
performance are the key issues in this design. You will be using private addressing in
your network.
Continued:
Ok…great…you just got your wonderful network designed and implemented, so now you
know why it needed to be adaptable: the “eccentric” president read an article in the
“Harvard Business Review” (yeah…he could almost understand the big words) and
wanted to implement a divisional team format. Sounds good to everyone but it is really
going to test your knowledge of networking to make it work. Every division will have
engineers, accountants, and sales people. Where before they all were in their own little
area connected to a switch, now they are scattered everywhere. You could buy tons of
switches to make that work OR you could use your knowledge of switching technology
to move them around nicely and easily. The new divisions are: north (5 engineers, 1
accountant, and 2 sales people), south (4 engineers, 1 accountant, and 2 sales people),
east (4 engineers, 1 accountant, and 2 sales people), west (5 engineers, 1 accountant, and
2 sales people), special projects/ R&D (4 engineers, 1 accountant, and 2 sales people),
and the administration/production staff (6 accountants, 1 sales person, and 19
production).
