Ubuntu Virtual machine IP and DNS Query method

It's a very simple experience, but it's a summary. Currently in the use of several Ubuntu virtual machines, but the trouble is that the virtual machine IP address is DHCP, will often change. If the direct manual configuration, suffer from do not know how the gateway and DNS configuration (because do not know the details of the virtual machine configuration), and ifconfig can only query Ubuntu IP address, and can not query DHCP DNS and gateway information. The workaround is also simple, using:

Nm-tool

This command is ready.
