As for how to divide IP addresses, you can click [Settings] - [Virtual Network Editor] of the virtual machine, select VMnet8 - NET mode, and then plan the subnet yourself.

My real host occupies an IP of 192.168.1.1, so my gateway should be set to: 192.168.1.2, and then the host can be set to: 192.168.1.3 or 1.4, etc. I set 192.168.1.4 here
