<para>By default, NixOS uses DHCP (specifically,
 | 
						||
<command>dhcpcd</command>) to automatically configure network
 | 
						||
interfaces.  However, you can configure an interface manually as
 | 
						||
follows:
 | 
						||
 | 
						||
<programlisting>
 | 
						||
networking.interfaces.eth0.ip4 = [ { address = "192.168.1.2"; prefixLength = 24; } ];
 | 
						||
</programlisting>
 | 
						||
 | 
						||
Typically you’ll also want to set a default gateway and set of name
 | 
						||
servers:
 | 
						||
 | 
						||
<programlisting>
 | 
						||
networking.defaultGateway = "192.168.1.1";
 | 
						||
networking.nameservers = [ "8.8.8.8" ];
 | 
						||
</programlisting>
 | 
						||
 | 
						||
</para>
 | 
						||
 | 
						||
<note><para>Statically configured interfaces are set up by the systemd
 | 
						||
service
 | 
						||
<replaceable>interface-name</replaceable><literal>-cfg.service</literal>.
 | 
						||
The default gateway and name server configuration is performed by
 | 
						||
<literal>network-setup.service</literal>.</para></note>
 | 
						||
 | 
						||
<para>The host name is set using <option>networking.hostName</option>:
 | 
						||
 | 
						||
<programlisting>
 | 
						||
networking.hostName = "cartman";
 | 
						||
</programlisting>
 | 
						||
 | 
						||
The default host name is <literal>nixos</literal>.  Set it to the
 | 
						||
empty string (<literal>""</literal>) to allow the DHCP server to
 | 
						||
provide the host name.</para>
