My Mac will not load most websites on any browser.

My MacBook Pro will not load most websites on safari, chrome, or Firefox. Major websites like google, YouTube, and Facebook, seem to work fine, but no other websites will load at all. It is not my WiFi, as all of my other devices on the same network are loading pages just fine. I cleared the history and website data and saw no improvement. I tried using network utility and put my school website into “ping” and this is what I got out:

I tried using look up as well and this is what it says:
