Different IP on each workstation

It seems that some offices all the workstations have the same IP to the outside world, and some have it where each workstation has it's own IP.  What are the differences in hardware and/or software between these two?

High level description:

This is generally something handled by the router. First you would need to purchase enough IP addresses (usually purchased in a range) and then set up a route for each external address to go to a different internal address (workstation).

What you are attempting to accomplish would determine what is needed. For example, you have a workstation acting like a web server then you would probably want it to have it's own external IP.

If i understand your doubt is why the workstations inside your private network have different IP´s.
That is because each machine needs to have a unique IP, you need to think as if each IP corresponded to a single apartment in a building, for instance, 1A has an IP, 1B has another IP, 2A as another IP and so on. The public IP will correspond to the building door from where all the apartments need to get in or get out, thats why the Outside world sees your building door and not the apartments door. This process is called the NAT ( Network Address translation ).

I hope this can clarified your question.

Yes, that makes perfect sense.  I'll forward this to my wife who is trying to print coupons and can only do 2 per IP.  :)

Can you clarify what do you want to accomplish? Or what do you want to know.

Sorry if I misunderstood.

My wife was wondering if we could set up our home network so that all the computers had different IPs so that she could go to this coupon website and print 2 coupons from each of our home computers.

Oh ok.
You have to use a proxy server.
With a proxy server you can receive a different IP from another network, your wife can´t do that because your public IP has been saved by the website, right?

Try this:
1º - Download this software:Tor
2º - Install it on your machine
3º - Run the Tor Software, a browser will open, on that browser try to access again to the        
      coupon site.

This is not granted because if I were the network admin where the site is installed, I probably used access rules on the firewalls.

But you could try and see what happens.

Basically what you are wanting to do is hide yourself behind a public proxy.  There are several sites out that that will do that for you.  Unfortunately I am at work where we block these sites so I can't really recommend one for you

You can do a google/bing or whatever search engine you prefer to find free proxy servers.

A couple that come up are:


There are others but you will have to decide which one is safe and works for you.
