<title>IPv6 Configuration</title>

|

<para>

IPv6 is enabled by default. Stateless address autoconfiguration is
|
||
|
|
used to automatically assign IPv6 addresses to all interfaces, and
|
||
|
|
Privacy Extensions (RFC 4946) are enabled by default. You can adjust
|
||
|
|
the default for this by setting
|
||
|
|
<link xlink:href="options.html#opt-networking.tempAddresses"><literal>networking.tempAddresses</literal></link>.
|
||
|
|
This option may be overridden on a per-interface basis by
|
||
|
|
<link xlink:href="options.html#opt-networking.interfaces._name_.tempAddress"><literal>networking.interfaces.<name>.tempAddress</literal></link>.
|
||
|
|
You can disable IPv6 support globally by setting:
|
||
|
|
</para>
|
||
|
|
<programlisting language="bash">
|
||
|
|
networking.enableIPv6 = false;
|
||
|
|
</programlisting>
|
||
|
|
<para>
|
||
|
|
You can disable IPv6 on a single interface using a normal sysctl (in
|
||
|
|
this example, we use interface <literal>eth0</literal>):
|
||
|
|
</para>
|
||
|
|
<programlisting language="bash">
|
||
|
|
boot.kernel.sysctl."net.ipv6.conf.eth0.disable_ipv6" = true;
|
||
|
|
</programlisting>
|
||
|
|
<para>
|

As with IPv4 networking interfaces are automatically configured via
|
||
|
|
DHCPv6. You can configure an interface manually:
|
||
|
|
</para>
|
||
|
|
<programlisting language="bash">
|
||
|
|
networking.interfaces.eth0.ipv6.addresses = [ {
|
||
|
|
address = "fe00:aa:bb:cc::2";
|
||
|
|
prefixLength = 64;
|
||
|
|
} ];
|
||
|
|
</programlisting>
|
||
|
|
<para>
|
||
|
|
For configuring a gateway, optionally with explicitly specified
|
||
|
|
interface:
|
||
|
|
</para>
|
||
|
|
<programlisting language="bash">
|
||
|
|
networking.defaultGateway6 = {
|
||
|
|
address = "fe00::1";
|
||
|
|
interface = "enp0s3";
|
||
|
|
};
|
||
|
|
</programlisting>
