It provides name resolution to all the containers that are on the host in bridge, overlay or MACVLAN networks. The Docker Cloud automatic DNS service resolves the service name to the correct IP on the overlay network, even if the container has moved or is now on a different host. The internal process is, essentially, still very similar to the one used by the standalone Swarm, only with less moving parts. Docker uses a DNS server for keep updated registries with its containers.
