Description
Work is underway in SwarmKit to support dynamic IP addresses for managers in the Raft implementation: https://github.com/docker/swarmkit/pull/1579
For dynamic IP addresses to be fully supported in SwarmKit, libnetwork will need to be updated to handle address changes in overlay networking.
This could support some interesting use-cases, like running swarm clusters of laptops attached to WiFi networks. Since developers often run these tools on their laptops, it would be very nice to support this use case smoothly.

Research direction
Start by reading the linked SwarmKit PR #1579 and the libnetwork overlay-networking implementation. Identify where peer or manager addresses are stored and updated, then define how address changes should propagate through existing overlay state. Done means dynamic manager addresses remain usable without disrupting overlay networking, with tests covering address changes.
