IPvlan network driver

The IPvlan network driver in Docker is a type of network driver that provides network isolation and allows containers to have their own MAC and IP addresses on a network. It operates at Layer 2 of the OSI model and enables containers to communicate directly with the physical network, bypassing the host’s networking stack.

The IPvlan network driver in Docker provides users with extensive control over IPv4 and IPv6 addressing within containers. It allows for the creation of isolated network segments with their own MAC and IP addresses, enhancing network security and segmentation capabilities.

The IPvlan driver gives users total control over both IPv4 and IPv6 addressing. The VLAN driver builds 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.

IPvlan is a new twist on the tried and true network virtualization technique. The Linux implementations are extremely lightweight because rather than using the traditional Linux bridge for isolation, they are associated to a Linux Ethernet interface or sub-interface to enforce separation between networks and connectivity to the physical network.

IPvlan offers 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 fewer moving parts. Removing the bridge that traditionally…
