How to configure Docker to start containers on a specific IP address range

This technical article addresses a common Docker networking question: how to change the default IP address range used for containers. It explains Docker's default bridge creation logic, its limitations in detecting network conflicts, and provides a step-by-step manual solution. The guide shows how to create and configure a custom bridge interface (e.g., br0) with a fixed IP subnet and instruct the Docker daemon to use it, including configuration for persistence across reboots on systems like Ubuntu.
