1. Difference between nat, bridge and host-only

nat: Internet connection possible

Virtual host---> Host----> Internet (Virtual host and host are parent-child relationship (Virtual host has no autonomy, if host has problems, virtual host cannot communicate with the outside world, inheritance relationship))

Pros: Virtual hosts are less likely to cause IP address conflicts

Disadvantages: Virtual hosts need to rely on host machines to be able to access external networks, and their independence is relatively poor.

Bridging: Internet connectivity

Virtual host---> Host----> Internet (Virtual host and host are parent-child relationship (Virtual host has autonomy, if there is a problem with the host, virtual host can contact the outside world by itself, cooperative relationship))

Advantages: Virtual hosts can communicate with the outside world without the help of host machines, and are relatively independent.

Disadvantages: Virtual hosts have the ability to communicate independently with the outside world, so it is easy to cause IP conflicts.

Host only: Can connect to a local area network
