Appendix C Connecting to the Internet 87
Using DSL, Cable Modem, or LAN Internet Connections
If you connect to the Internet using a DSL or cable modem or Ethernet LAN, ask your
ISP or network administrator how you should configure your Internet connection.
 Manually: With a manual configuration, your ISP or network administrator provides a
static IP address and other information that you enter in Network preferences.
 Using Dynamic Host Configuration Protocol (DHCP): With a DHCP configuration,
the DHCP server automatically enters the information for you.
 Using Point-to-Point Protocol over Ethernet (PPPoE): If you use a DSL modem and
need a user name and password to connect to the Internet, you may need to
configure your network to use PPPoE.
Make sure you have the information from your ISP available as you configure your
network (see page 80).
To set up Network preferences for the built-in Ethernet port:
1 Choose Apple () > System Preferences from the menu bar.
2 Click Network.
3 Choose Network Port Configurations from the Show pop-up menu.
