Now a gratuitous/unsolicted ARP is sent, there's no need to
use an IPv4-based MAC address to preserve arp-cache mappings
between an endpoint's IP addresses and its MAC addresses.
Because a random MAC address is used for the default bridge,
it no longer makes sense to derive container IPv6 addresses
from the MAC address. This "postIPv6" behaviour was needed
before IPv6 addresses could be configured, but not now. So,
IPv6 addresses will now be IPAM-allocated on the default
bridge network, just as they are for user-defined bridges.

Libnetwork provides a native Go implementation for connecting containers
The goal of libnetwork is to deliver a robust Container Network Model that provides a consistent programming interface and the required network abstractions for applications.
There are many networking solutions available to suit a broad range of use-cases. libnetwork uses a driver / plugin model to support all of these solutions while abstracting the complexity of the driver implementations by exposing a simple and consistent Network Model to users.
