46 CHAPTER 5: CONFIGURING THE 56K LAN MODEM You Should Have This Information If you want to set up a connection to an ISP, you will need: s Your ISP's telephone access number. s Your user name, password and DNS address (if your service provider requires a specific DNS address). Determine Whether You Use Dynamic or Static IP Addresses Your setup procedure varies depending upon whether you are using a dynamic or a static IP address. A static IP address is a permanent, manually-assigned address recognized by a remote server, such as a corporate LAN or an ISP. By default, your 56K LAN Modem dynamically assigns an IP address to each computer. If you have been accessing a remote server via a static IP address prior to installing your 56K LAN Modem, you may be required to perform additional configuration steps. The first step is to determine your static versus dynamic IP addressing scenario. If you determine that your computer has a static IP address, refer to "Setting Up Your Computer If You Have a Static IP Address." If your computer has a dynamic IP address, you may begin configuring the 56K LAN Modem directly. Refer to "Configuring the 56K LAN Modem for the Typical Configuration". Determine your IP address type as follows: s For Windows 95, 98 and NT 4.0 Users: From the Start menu, select Settings and then Control Panel. Double-click Network. Select TCP/IP for the Ethernet card associated with your 56K LAN Modem and then click Properties. Select the IP Address tab. If the radio button labeled Obtain an IP address automatically (Windows 95 and 98) or Obtain an IP address from a DHCP server (Windows NT 4.0) is selected, then your computer has a dynamically assigned IP address. You are ready to continue directly with "Configuring the 56K LAN Modem for the Typical Configuration". If the radio button labeled Specify an IP address is selected, your computer has a static IP address. s For Mac Users: From the Apple menu, select Control Panels, and double-click TCP/IP. Choose Ethernet from the Connect Via pop-up menu, if it is not already chosen. If the Configure pop-up menu is set to Using DHCP Server, then your computer has a dynamically assigned IP address. You are ready to continue directly with "Configuring the 56K LAN Modem for the Typical Configuration". If Configure is not set to Using DHCP Server, and you have specific values listed in any of the following fields: IP address, Subnet mask, Router address, or Name server address, then your computer has a static IP address. s For Windows 3.11 Users: From the Program Manager, double-click the Network program group icon. Double-click the Network Setup icon. Click the Drivers button. Highlight the MS TCP/IP - 32.X entry and click Setup. If Enable Automatic DHCP Configuration is checked, then your computer has a dynamic IP address. You are ready to continue directly with "Configuring the 56K LAN Modem for the Typical Configuration". If an IP address is entered in the IP Address box, then your computer has a static IP address.
