If you want to get all the information about your current network connection in an easy to read textual format you should learn how to use ipconfig.exe tool. It is a powerful and at the same time easy to use tool.

To run it you need to first launch Command Prompt. On older Windows versions (before 8) this could be done from Start menu: select Run... then type cmd.exe and press Enter. On newer Windows versions (8 or newer) you can just type cmd.exe in search and select Command Prompt result.

In Command Prompt window type ipconfig /a. This will give you information about all network connections on your computer. Below you will find a list of fields which are shown for each network connection and what they mean.
