Nassau provides you with a quick view of multiple network details.
It resides in the systray, and the collected details can be viewed by just hovering over the icon. The details provided are the username, computer name and workgroup/domain. Additionally, for every network adapter, it will display all IP, gateway and DNS server addresses. You can also have these details displayed from a more refined window by double-clicking the icon. It is a lightweight and straightforward option to display network info without the need for clicking around.
For those that prefer, you can start Nassau.exe /s which only shows the dialog excluding the taskbar icon. Nassau.exe /e report.txt will create a text file that includes all the information.
Nassau is a great little tool for extracting network details without taking up too many resources.
