Router+Switch=??????

[AMD beginner]

I have a switch which i bought stupidly at radioshack, and now that i know i need two ip's for it, can i just get a router, get 4 ip's, and then connect them to the switch?
or some sort of stuff like that.
IF U CAN, HOW DO U DO THAT.

and if u can't how cna i not waste the switch.

Like can getting a hub work?

If it is just a switch, then just buy a router, it will take the 1 IP address and split it into as many as you require.

I have a Linksy's switch and separate Linksy's router. Works great and handles the IP's easily, all by itself (the router).

You don't need to get additional IP's. A router allows you to separate the public address space (the IP you get from your ISP) from a private address space (what you do on your side of the router). If you get a simple Cable/DSL router, you will have all you need. You then have a couple of options. You can assign your own IP's on each computer by specifying them in the network properties or you can let DHCP assign the numbers dynamically if the router you get supports DHCP [most of them do]. Just bear in mind that you want a simple router and not a router/switch combination. You already have the switch. A Linksys BEFSR11 will do the trick nicely.

You can use a hub in place of the switch and you probably would not notice the difference unless you're really pushing the limits on your bandwidth. You've already got the switch so it's irrelevant.

Hope this helps.

Sorry, the spacing of the above message did not work. Computer 1 and Computer 2 should branch out from the switch.

2 of my pc's were already on the switch, my 3rd wasn't. I put the router by 3rd pc, and ran the cable over to the switch. Router handled it all, assigning IP addresses.
