7.15. Network Configuration
Fedora contains support for both IPv4 and IPv6. However, by default, the installation program configures network interfaces on your computer for IPv4, and to use DHCP via
does not support IPv6. If your network only supports IPv6 you should use
after installation to configure your network interfaces.
Setup prompts you to supply a host name and domain name for this computer, in the format
. Many networks have a DHCP (Dynamic Host Configuration Protocol) service that automatically supplies connected systems with a domain name, leaving the user to enter a hostname.

To set up a network that is behind an Internet firewall or router, you may want to use
for your Fedora system. If you have more than one computer on this network, you should give each one a separate host name in this domain.
You may give your system any name provided that the full hostname is unique. The hostname may include letters, numbers and hyphens.
On some networks, the DHCP provider also provides the name of the computer, or hostname. The complete hostname includes both the name of the machine and the name of the domain of which it is a member, such as

domain name is
If your Fedora system is connected
to the Internet, you must pay attention to additional considerations to avoid service interruptions or risk action by your upstream service provider. A full discussion of these issues is beyond the scope of this document.
The installation program does not configure modems. Configure these devices after installation with the
utility. The settings for your modem are specific to your particular Internet Service Provider (ISP).
7.15.1. Manual configuration
Installations that require certain advanced configurations cannot succeed without network connectivity during the installation process, for example, installations on systems with ISCSI drives. In situations where successful installation depends upon correct network settings, the installation program will present you with a dialog that allows you to confirm these details.

If your network does not have DHCP enabled, or if you need to override the DHCP settings, select the network interface that you plan to use from the
menu. Clear the checkbox for
