 IPv6 support globally by setting:
 
 ```nix
-networking.enableIPv6 = false;
+{
+  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;
+{
+  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;
-} ];
+{
+  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";
-};
+{
+  networking.defaultGateway6 = {
+    address = "fe00::1";
+    interface = "enp0s3";
+  };
+}
 ```
