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 [](#opt-networking.tempAddresses). This option +may be overridden on a per-interface basis by +[](#opt-networking.interfaces._name_.tempAddress). You can disable +IPv6 support globally by setting: + +```nix +networking.enableIPv6 = false; +``` + +You can disable IPv6 on a single interface using a normal sysctl (in +this example, we use interface `eth0`): + +```nix +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: + +```nix +networking.interfaces.eth0.ipv6.addresses = [ { + address = "fe00:aa:bb:cc::2"; + prefixLength = 64; +} ]; +``` + +For configuring a gateway, optionally with explicitly specified +interface: + +```nix +networking.defaultGateway6 = { + address = "fe00::1"; + interface = "enp0s3"; +}; +``` + +See [](#sec-ipv4) for similar examples and additional information. |
