BEFW11S4 VER 3 USER GUIDE_2nd.qxd 10/15/02 10:33 AM Page 2 Instant WirelessTM Series IP Addresses What’s an IP Address? IP stands for Internet Protocol. Every device on an IP-based network, including PCs, print servers, and routers, requires an IP address to identify its “location,” or address, on the network. This applies to both the WAN and LAN connections. There are two ways of assigning an IP address to your network devices.
BEFW11S4 VER 3 USER GUIDE_2nd.qxd 10/15/02 10:33 AM Page 3 Wireless Access Point Router with 4-Port Switch Dynamic IP Addresses A dynamic IP address is automatically assigned to a device on the network, such as PCs and print servers. These IP addresses are called “dynamic” because they are only temporarily assigned to the PC or device. After a certain time period, they expire and may change.
