Let say that a person has made a comment on a Facebook group and in the browser address bar it will have a link with the following format. If someone clicked on this link, it will jump straight to the public comment (this is just a sample link):

I have read that ISP can see the person's IP address visited the domain facebook.com
but will ISP got the full link of the comment link above?
I ask this question because I'm doubt whether I should use VPN to prevent this information leaked to ISP.
