My router configured by ISP tech and it is set to get DNS server address automatically from upstream. Is there is a way to find out the IP address of the dns server used by my router which is located at 192.168.1.1? Is there Linux, Unix, Apple OS X, or MS-Windows command that I can use get the same information?
