     50        Udev normally assigns network card interface names based
     51        on system physical characteristics such as enp2s1. If you are
     52        not sure what your interface name is, you can always run
     53        <command>ip link</command> after you have booted your system.
     54      </para>
     55
     56      <para>
     57        For most systems, there is only one network interface for
     58        each type of connection.  For example, the classic interface
     59        name for a wired connection is eth0.  A wireless connection
     60        will usually have the name wifi0 or wlan0.
     61      </para>
     62
     63      <para>
     64        If you prefer to use the classic or customized network interface names,
     65        there are three alternative ways to do that:</para>
     66
     67      <itemizedlist>
     68        <listitem>
     69          <para>
     70            Mask udev's .link file for the default policy:
     71<screen role="nodump"><userinput>ln -s /dev/null /etc/systemd/network/99-default.link</userinput></screen>
     72          </para>
     73        </listitem>
     74
     75        <listitem>
     76          <para>
     77             Create a manual naming scheme, for example by naming the
     78             interfaces something like "internet0", "dmz0", or "lan0".
     79             For that, create .link
     80             files in /etc/systemd/network/, that choose an explicit name or a
     81             better naming scheme for one, some, or all of your interfaces.
     82             For example:
     83          </para>
     84
     85<screen role="nodump"><userinput>cat &gt; /etc/systemd/network/10-ether0.link &lt;&lt; "EOF"
