Changing The Ip Address Of The Router - D-Link DSL-500 User Manual

Please note that when using the default IP address as in the above example, the first three numbers in the IP
address must always be the same with only the fourth number changing (for a Class C network). This is because
the first three numbers define the network IP address (all machines must belong to the same IP network), while
the last number denotes the host IP address (each computer must have a unique address to distinguish it on the
network). Also note that the subnet mask is the same for all machines and the default gateway address is the
LAN IP address of the Router.
It is a good idea to make a note of each device's IP address for reference during troubleshooting or when adding
new stations or devices.
Using DHCP
The second way to use the default settings is to allow the Router to automatically assign IP addresses to your
computers using DHCP. To do this, simply make sure your computers' IP addresses are set to 0.0.0.0 (under
Windows, choose the option Obtain an IP address automatically in the TCP/IP network component described
above). When the computers are restarted, their IP settings will automatically be assigned by the Router. The
Router is set by default to use DHCP. See the discussion in Chapter 5 for information on how to use configure
the Router for DHCP.

Changing the IP Address of the Router

If you choose to change the IP address of the Router you will need to access the device directly via the RS-232
connection using a terminal emulation interface (such as Microsoft HyperTerminal used in the sample screen
captures). Your terminal parameters will need to be set to:
C. VT-100/ANSI compatible
D. Terminal keys enabled
E. 9,600 baud
F. 8 data bits
G. No parity
H. One stop bit
Connect a standard RS-232 (DB-9 to DB-9) cable to the Router's RS-232 port on the rear panel, connect the
other end to a PC with a terminal emulation program already installed. Power on the Router and launch the
emulation program. The terminal emulator will display system information while the unit undergoes self-testing.
When 192.168.0.1> appears on the screen the unit has completed its self-test. In this mode, the default IP
address 192.168.0.1 and an angle bracket ("greater than") will appear each time the Enter key is depressed.
