<title>IPv6 Configuration</title>

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 <xref linkend="opt-networking.tempAddresses"/>.
|
|
This option may be overridden on a per-interface basis by
|
|
<xref linkend="opt-networking.interfaces._name_.tempAddress"/>.
|
|
You can disable IPv6 support globally by setting:
|
|
<programlisting>
|
|
<xref linkend="opt-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>
|
|
<xref linkend="opt-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:
|
|
<programlisting>
|
|
<link linkend="opt-networking.interfaces._name_.ipv6.addresses">networking.interfaces.eth0.ipv6.addresses</link> = [ {
|
|
address = "fe00:aa:bb:cc::2";
|
|
prefixLength = 64;
|
|
} ];
|
|
</programlisting>
|
|
</para>
|
|
|
|
<para>
|
|
For configuring a gateway, optionally with explicitly specified interface:
|
|
<programlisting>
|
|
<xref linkend="opt-networking.defaultGateway6"/> = {
|
|
address = "fe00::1";
|
|
interface = "enp0s3";
|
|
};
|
|
</programlisting>
|
|
</para>
