What types of networks are available in Docker?

In Docker, there are several main types of networks used to organize container interaction:

• bridge — the default standard network for containers on the same host. Containers in the same bridge network can communicate with each other by name.
• host — the container uses the host's network stack directly, without isolation. This increases performance but reduces security.
• none — the container runs without a network interface.
• overlay — used to connect containers running on different hosts in a Docker Swarm or Kubernetes cluster, allowing them to communicate as if in the same network.
• macvlan — allows containers to have their own MAC addresses and appear as separate devices on the physical network.

The choice of network depends on the requirements for isolation, performance, and application architecture.
