The Macvlan and Ipvlan drivers are currently in experimental mode in order to incubate Docker users use cases and vet the implementation to ensure a hardened, production ready driver in a future release. Libnetwork now gives users total control over both IPv4 and IPv6 adressing. The VLAN drivers build on top of that in giving operators complete control of layer 2 VLAN tagging and even Ipvlan L3 routing for users interested in underlay network integration. For overlay deployments that abstract away physical constraints see the [multi-host overlay ](https://docs.docker.com/engine/userguide/networking/get-started-overlay/) driver.
Macvlan and Ipvlan are a new twist on the tried and true network virtualization technique. The Linux implementations are extremely lightweight because rather then using the traditional Linux bridge for isolation, they are simply associated to a Linux Ethernet interface or sub-interface to enforce seperation between networks and connectivty to the physical network.

The Linux implementations are extremely lightweight because rather than using the traditional Linux bridge for isolation, they are simply associated to a Linux Ethernet interface or sub-interface to enforce seperation between networks and connectivity to the physical network.
Macvlan and Ipvlan offer a number of unique features and plenty of room for further innovations with the various modes. Two high level advantages of these approaches are, the positive performance implications of bypassing the Linux bridge and the simplicity of having less moving parts. Removing the bridge that traditionally resides in between the Docker host NIC and container interface leaves a very simple setup consisting of container interfaces, attached directly to the Docker host interface. This result is easy access for external facing services as there is no port mappings in these scenarios.
