D-Link DFL-600 - Manual (Page 22)

IP Settings Mode This drop-down menu determines how the DFL-
600 will obtain its IP address information. The
fields where you will enter the information will
change, as appropriate, to reflect the mode you
have selected. The page shown above is in
Dynamic mode.
Dynamic allows the DFL-600 to get its IP
address information from your ISP using the
Dynamic Host Configuration Protocol (DHCP).
Use this setting if your ISP instructs you to use
DHCP or to automatically obtain an IP address.
A server on your ISP’s network will then
automatically send the necessary IP address
information to your DFL-600.
Static allows you to manually enter the
necessary IP address information. Use this
setting if your ISP has permanently assigned an
IP address to your connection.
PPPoE allows you to enter a Username and
Password for a Point-to-Point Protocol over
Ethernet (PPPoE) internet connection. Use this
setting if your ISP has provided you with an
ADSL modem that operates in Bridge mode.
IP Address This is the current IP address used to identify
your ‘location’ on the Internet. It is assigned by
your ISP, or entered statically by you. IP
addresses work in combination with a subnet
mask, described below.
Subnet Mask A subnet mask is a number, in the same form as
an IP address, that is used to mathematically
separate a range of IP addresses into a Network
portion and a Node portion. The Node portion
identifies a specific device on the Network
− in
this case, the DFL-600.
