DSL/Network question

I have two computers networked together in my home office. I recently had someone come in and install DSL for me. The DSL line plugs into the 4 port switch that links my networked computers together. I am now able to access the internet over both computers on my network.

My question is this:

Can I add more computers to my network and access the internet thru my DSL connection on these new computers without paying additional charges for the DSL? The reason I ask is this... The two computers that are already networked together have different IP addresses. The IP addresses only differ by one digit. I added a new computer to the network myself and assigned it an IP address the same as the other two except for the last digit which I incremented by one (so the last 3 digits of the IP address on the three computers is 240, 241 and 242). Adding the computer to the network seems to have gone fine except that I cannot access the internet from it. Is the IP address something that I have to get the DSL provider to set up for me? Do I need to pay extra for it?

I guess it makes sense that the providers of high speed internet access would charge by computer otherwise large companies could just sign up once and use the connection for hundreds of computers on the network, right?

On the other hand, I have networked computers together before and used Microsoft's Internet Connection Sharing to access the internet from multiple computers with just one dial-up connection.
 
Your post is devoid of some info. There are three address ranges set aside for local use only. 10.X.X.X, 172.16.X.X, and 192.168.X.X. Windows uses 169.254.X.X AS an IP address to a DHCP client that cannot find a DHCP server. If the address you added to the third PC is not in these ranges, in other words, since you gave very little info, if you gave a third machine a legitimate WAN IP, then you need to take it off. You can pay your provider for a third IP, or you can buy a router (Does what you did when you used ICS).
