Linux has easy commands to find the DHCP server IP address via a command prompt.
Is there anything for Windows?
The DHCP server used to obtain an address is included in the output of
ipconfig /all | findstr /C:"DHCP Server"
If your computer has static IP then the
ipconfig /all will not show the DHCP server on your network. In this case you can use the following command line to display it.
netsh dhcp show server
