English Actions
Create the <filename>/etc/hostname</filename> file and enter a hostname by running:
<userinput>echo "<replaceable>&lt;lfs&gt;</replaceable>" &gt; /etc/hostname</userinput>
<replaceable>&lt;lfs&gt;</replaceable> needs to be replaced with the name given to the computer. Do not enter the Fully Qualified Domain Name (FQDN) here. That information is put in the <filename>/etc/hosts</filename> file.

Decide on a fully-qualified domain name (FQDN), and possible aliases for use in the <filename>/etc/hosts</filename> file. If using static IP addresses, you'll also need to decide on an IP address. The syntax for a hosts file entry is:
<literal>IP_address myhost.example.org aliases</literal>
Unless the computer is to be visible to the Internet (i.e., there is a registered domain and a valid block of assigned IP addresses&mdash;most users do not have this), make sure that the IP address is in the private network IP address range. Valid ranges are:
<literal>Private Network Address Range Normal Prefix
10.0.0.1 - 10.255.255.254 8
172.x.0.1 - 172.x.255.254 16
192.168.y.1 - 192.168.y.254 24</literal>
x can be any number in the range 16-31. y can be any number in the range 0-255.
A valid private IP address could be 192.168.1.1.
If the computer is to be visible to the Internet, a valid FQDN can be the domain name itself, or a string resulted by concatenating a prefix (often the hostname) and the domain name with a <quote>.</quote> character. And, you need to contact the domain provider to resolve the FQDN to your public IP address.
Even if the computer is not visible to the Internet, a FQDN is still needed for certain programs, such as MTAs, to operate properly. A special FQDN, <literal>localhost.localdomain</literal>, can be used for this purpose.
Create the <filename>/etc/hosts</filename> file using the following command:
<userinput>cat &gt; /etc/hosts &lt;&lt; "EOF"
<literal># Begin /etc/hosts

<replaceable>&lt;192.168.0.2&gt;</replaceable> <replaceable>&lt;FQDN&gt;</replaceable> <replaceable>[alias1] [alias2] ...</replaceable>
::1 ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

# End /etc/hosts</literal>
EOF</userinput>
The <replaceable>&lt;192.168.0.2&gt;</replaceable> and <replaceable>&lt;FQDN&gt;</replaceable> values need to be changed for specific uses or requirements (if assigned an IP address by a network/system administrator and the machine will be connected to an existing network). The optional alias name(s) can be omitted, and the <replaceable>&lt;192.168.0.2&gt;</replaceable> line can be omitted if you are using a connection configured with DHCP or IPv6 Autoconfiguration, or using <literal>localhost.localdomain</literal> as the FQDN.
The <filename>/etc/hostname</filename> does not contain entries for <literal>localhost</literal>, <literal>localhost.localdomain</literal>, or the hostname (without a domain) because they are handled by the <systemitem class='library'>myhostname</systemitem> NSS module, read the man page <ulink role='man' url='&man;nss-myhostname.8'>nss-myhostname(8)</ulink> for details.
The ::1 entry is the IPv6 counterpart of 127.0.0.1 and represents the IPv6 loopback interface.
