How to query the IP address and DNS of Ubuntu virtual machine, ipdns of ubuntu Virtual Machine

This is a very simple experience, but let's summarize it. Currently, several Ubuntu virtual machines are used, but the trouble is that the IP address of the virtual machine is DHCP, which often changes. If you directly configure Manual, you do not know how to configure the gateway and DNS (because you do not know the details of the virtual machine configuration), and ifconfig can only query the Ubuntu IP address, the DNS and gateway information in DHCP cannot be queried. The solution is also very simple. Use:

Nm-tool

This command is enough.
