There are several ways you can determine your IP address information:
IPCONFIG
  1. Start / Run / cmd
  2. IPCONFIG /ALL
This opens a command window. One advantage is that you can send the information to a text file (IPCONFIG /ALL > c:\ip.txt)
But sometimes the window shows show much information you need to scroll around to fine it.
