- Closes #752. - Currently, there is no way to specify a custom MAC address for a container's network interface and the MAC address is auto-generated by the system. - Use Cases - **Network Testing**: Developers testing network-dependent applications that need predictable MAC addresses - **License Management**: Running containerized software with MAC-based license keys - **Network Automation**: Scripts and tools that expect specific MAC addresses for configuration - **Debugging**: Consistent MAC addresses across container restarts for easier troubleshooting
