Explain the purpose and features of the host type network in Docker containers

A host network in Docker allows a container to use the host's network stack directly, without isolation. This means the container does not get a separate IP address but uses the IP and ports of the host machine.

Features and purpose:

• High network performance — no additional NAT layer, reducing latency.
• Direct access to host network interfaces — useful if the container needs to listen on ports already occupied on the host or work directly with network services.
• No network isolation — the container and host share the same network, which can be risky from a security perspective.

Example of usage:

docker run --network host my_image

Used when maximum network performance is important or access to specific host network resources is required.
