Connect 2 computers with 2 different IP addresses together via Network Switch?

sitting here wondering why on earth you would have your network configured this way should be modem to switch , switch to pc

No it is not.

The difference between a switch and a router is called NAT - Network Address Translation

A router presents only one IP address to the WAN side, regardless of how many computers are connected on the LAN side. The router TRANSLATES the LAN side IP addresses to do this. As far as the modem is concerned, there is only one computer connected to it.

A switch passes the IP address though, so the modem, which can only work with one address at a time, shuts the other computer out.

Hope that helps

you are able to no longer have 2 routers on the comparable community. it won't artwork. A router takes a public ip, and spilts them right into a set of dumrb inner maximum ip addressing utilising something called NAT (call handle table). in case you attempt to place one router in the back of yet another, the NAT tables does no longer be waiting to correctly distribute the packets. What you desire is a change or a hub. Peferable a change, using fact a change does not have the themes a hub does. (that could be a various question). you would be waiting to bypass into the router configuration, and turn off the router functionality, so effectively that could be a change. desire that helps

To "split" an Internet connection you must have a router, not just a switch.

Once your Internet connection has been split by a router, you can have as many switches as you want behind it.

As for connecting two PCs directly, you need a crossover cable.

I recommend buying a router, just a simple wireless-g linksys or netgear for $40 on sale at a retail store.
