This document discusses Docker networking features in version 1.12, including load balancing with IPVS and VTEP, embedded DNS, and round robin load balancing of containers. It also covers Docker libnetwork and networking drivers like overlay and host. Encryption of overlay networks with IPSEC is mentioned. Limitations of using swarm-scoped networks with `docker create` and `docker run` are noted. Load balancing at L4 and L7 using IPVS on the VTEP is discussed, as well as integration with other load balancers and Kubernetes L7 proxy.
