On some networks, the DHCP provider also provides the name of the computer, or hostname. To specify the hostname, select Manual and type the complete name in the box. The complete hostname includes both the name of the machine and the name of the domain of which it is a member, such as machine1.example.com. The machine name (or "short hostname") is machine1, and the domain name is example.com.

To set up a home network that is behind an Internet firewall or router, you may want to use hostname.localdomain 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.

	Valid Hostnames
	You may give your system any name provided that the full hostname is unique. The hostname may include letters, numbers and hyphens.

If your Fedora system is connected directly 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.
