Do all the computers in the company have Ip addresses?

The IP address is definitely different, but just enjoy surfing the Internet through the router, that is, set up a small LAN, through which you can set your own IP address.

For example, the common intranet IP 192. 168.x.x, x can be set by the router itself.

This should be the same as the first three, that is to say, in the same network segment, the IP is 192. 168.0.x, and the IP difference between the four computers is the last one.
