IPv6 Configuration
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
. This option may be
overridden on a per-interface basis by
. You
can disable IPv6 support globally by setting:
networking.enableIPv6 = false;
You can disable IPv6 on a single interface using a normal sysctl (in
this example, we use interface eth0):
boot.kernel.sysctl."net.ipv6.conf.eth0.disable_ipv6" = true;
As with IPv4 networking interfaces are automatically configured via
DHCPv6. You can configure an interface manually:
networking.interfaces.eth0.ipv6.addresses = [ {
address = "fe00:aa:bb:cc::2";
prefixLength = 64;
} ];
For configuring a gateway, optionally with explicitly specified
interface:
networking.defaultGateway6 = {
address = "fe00::1";
interface = "enp0s3";
};
