Running OpenDNS on a University ISP

So I live in an apartment on campus at my school. We have internet provided by the school itself. It's the type where I need to verify my credentials at each login. I did set up a router that allows me to bypass this. I've tried using OpenDNS servers because apparently this is the only way for me to be able to connect my Chromecast to the internet. However, whenever I input the DNS servers into my router, connectivity is shot and wont work until I revert back to ISP settings. Any idea why or how I can bypass this?

  What you're doing is really an inappropriate use of OpenDNS.  You do not own the network, and that's probably why your attempt to use OpenDNS is being blocked, probably upstream by their firewall.

  OpenDNS is a service for networks you own, not for your devices in other networks.

  What you are telling us shows that the network admins are professionals who exactly configured how they want their network being used.  That said, you'll have to refer to them for any related matters, especially "bypassing".

  You can check if you could use OpenDNS at all though:

  nslookup -type=txt which.opendns.com. 208.67.220.220nslookup -type=txt -port=443 which.opendns.com. 208.67.220.220
  nslookup -type=txt -port=5353 which.opendns.com. 208.67.220.220

  If all of these return "I am not an OpenDNS resolver", then you're out of luck, else not.

  "apparently this is the only way for me to be able to connect my Chromecast to the internet."

  Why do you think it is? Did you prove it?

  The commands again, they were broken:

  nslookup -type=txt which.opendns.com. 208.67.220.220
  nslookup -type=txt -port=443 which.opendns.com. 208.67.220.220
  nslookup -type=txt -port=5353 which.opendns.com. 208.67.220.220

  rotblitz,

  thank you for your response. honestly the only reason why i say this is the only was is because by word of mouth from other students, this is what i've heard. I'll try these commands though.
