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:
■Your ISP’s telephone access number.
■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:
■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.
■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.
■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.
