Problem

Given a Docker networking setup with containers attached to custom bridges, evaluate which statement regarding container reachability via hostname vs IP is false.

Asked in the CoderPad Online Assessment stage. Explain how Docker's embedded DNS, bridge isolation, and network membership affect reachability. If answer choices are provided, select the false statement and briefly justify it.
