5. Press the ! key to abort the DHCP process and display a prompt. If
you don't abort the DHCP process, it will fail after two minutes, and
eventually a prompt will appear.

The monitor's prompt is the + character. You can enter
h at the prompt for a complete list of supported
commands.
6. At the prompt, type xip:<safe IP address>
The xip command saves the IP address in flash memory. In general,
you only need to assign an IP address to your board once. However,
you can change it at any time by issuing another
xip command. You
can also use the commands xsubnet and xgateway to assign
subnet and gateway addresses, but setting these addresses is not
usually necessary.
7. Type xdhcp:off to disable the board from attempting to
obtain the IP address using DHCP in the future. (You can re-enable
DHCP later, using the
xdhcp:on command.)
8. Type CTRL+C to terminate the JTAG terminal session and
disconnect from the monitor program, then close the Nios II
command shell.
9. Press the SW8 button labeled CPU Reset to reboot the Nios II
processor and start the web server using the new IP address. The
LCD screen displays the static IP address assigned to the board,
along with other status messages.
The web server is now ready to display pages using the IP address you
assigned. See
“Browsing to Your Board” on page B–5 to continue.
Point–to–Point Connections
All boards are factory programmed with a default IP address of 10.0.0.51
stored in flash memory. The 10.0.0.x subnet is conventionally reserved for
development, test, and prototyping. If DHCP fails or is aborted, the board
uses this static IP address. The LCD screen displays status messages to
indicate when the web server starts running using the default IP address.
Your host computer and the development board are the only two devices
connected to this simple point-to-point network. For most host operating
systems, it is necessary to assign your host computer an IP address on the
same subnet as the board. For example, the address 10.0.0.1 will work
fine. Any address in the 10.0.0.x subnet will work, and there is no
possibility of conflicting with another device on the network. After
