D-Link DFL-600 Manual page 16

This menu allows you to select the type of connection your ISP provides.
Many ISPs use the PPPoE (Point-to-Point Protocol over Ethernet) for DSL
connections, while many Cable ISPs use DHCP (Dynamic Host
Configuration Protocol). DHCP assigns an IP address for your Internet
connection each time you log on (and is therefore, a dynamic IP address).
DHCP is referred to as Dynamic IP address on the DFL-600. The Setup
Wizard will open a page with the appropriate fields for the entry of your ISP
contact information, depending upon which of the three options you choose.
The Static IP address click-box is used to enter a permanent IP address that
is assigned by your ISP. If your ISP assigns you a permanent IP address,
choose this option.
Click Next to continue.
