1. you can get a switch which would connect to the modem allowing you to connect more than 1 computer via ethernet. 2. get a Router connects to the modem and lets you set up 4 computers via ethernet and also gives you wireless access. |
A modem does not have a restriction on how many IPs it can process. A modem is a layer 1 device which converts one type of physical medium to another. In the case of a cable modem, the modem converts the signaling used over coax cabling to Ethernet. Same goes with a DSL modem or a T1 modem. The restriction about how many IPs are supported over a particular circuit is from the ISP provisioning of your circuit. Most home services only have one IP allotted by the ISP. You can place a switch on the modem and wire up as many devices as you want. How may of those devices which will receive an IP is dependent on your service. If you have only 1 IP allotted, only one device will get an IP.
The use or SOHO routers is because of the 1 IP limitation of most home services. A SOHO router does a NAT overload where it can map multiple internal IP addresses to a single public IP. This allows multiple devices on your internal LAN to share the same public IP.
