Is there any way to determine a users DNS servers from a web page?

I am curious how I could detect a users DNS servers from my website. Is there any way to know? Any possible way?

No. By the time the user initiates the request to your server, the DNS lookup is already finished (or they wouldn't know the address of your server).

I suppose it's theoretically possible to abuse Javascript or other content in order to breach the security of the user's machine and try to fetch its configuration data, but I doubt you will get much help with that here.
