- 2. Docker 1.9.0 • New top-level UX & API : docker network • Support for multiple micro-segmented networks • Built-in multihost networking using VXLAN based overlay driver • Support for third party network plugins • Ability to dynamically connect containers to multiple networks • Pluggable and user-defined IP address mgmt • Integration with Docker Swarm
- 3. Docker 1.10.0 • Service Discovery using embedded DNS • IP stability using `--ip / --ipv6` option • Network-scoped Alias support • `—link` support in user-defined networks • Network isolation using `--internal` option • Multi-host networking in all supported kernels (3.10+) • Integration with Docker Compose
- 4. Docker 1.11.0 • Built-in load-balancing using DNS-RR • Service Discovery for IPv6 (AAAA Records) • Experimental Macvlan & IPVlan drivers
