# Network Configuration

If you do not have a network card, you will not see this screen. Skip ahead to the section called Firewall Configuration.

If you have a network card and you have not already configured your networking, you now have the opportunity (as shown in Figure 3-11).

If you have multiple devices, you will see a tab for each device. You may switch between devices (for example, between eth0 and eth1) and the information you provide on each tab will be specific to each device.

Indicate if you would like to configure your IP address using DHCP (Dynamic Host Configuration Protocol). If you select Activate on boot, your network interface will be started when you boot. If you do not have DHCP client access or you are unsure what to provide here, please contact your network administrator.

Next enter, where applicable, the IP Address, Netmask, Network, and Broadcast addresses. If you are unsure about any of these, please contact your network administrator.

| Note
| Do not use the numbers as seen in this sample configuration. These values will not work for your own network configuration. If you are not sure what values to enter, contact your network administrator for assistance.

If you have a fully qualified domain name for the network device, enter it in the Hostname field.

| Tip
| Even if your computer is not part of a network, you can enter a hostname for your system. If you do not take this opportunity to enter in a name, your system will be known as `localhost`.

Finally, enter the Gateway and Primary DNS (and if applicable the Secondary DNS and Ternary DNS) addresses.
