<title>IPv6 Configuration</title>
<para>IPv6 is enabled by default. Stateless address autoconfiguration
is used to automatically assign IPv6 addresses to all interfaces. You
can disable IPv6 support globally by setting:
<programlisting>
networking.enableIPv6 = false;
</programlisting></para>
<para>You can disable IPv6 on a single interface using a normal sysctl (in this
example, we use interface <varname>eth0</varname>):
<programlisting>
boot.kernel.sysctl."net.ipv6.conf.eth0.disable_ipv6" = true;
</programlisting>
</para>
