Keeping a log of network details for a computer can prove useful for future references and especially when it comes to troubleshooting or reinstalling Windows. Here is a simple way to record the IP address, the default gateway, IP addresses of DNS servers and other basic details related to a system :
1. Open Windows command prompt.
2. Simply type in : ipconfig/all > d:\ipdetails.txt
3. The output of this will not be shown in the command prompt but all the details that are displayed by this command will be stored in a text file named ipdetails in this example.
4. Store the file somewhere safe so that it can be retrieved quickly.
