Of course, I don't know about college.
Generally, schools access the local education metropolitan area network, access the education bureau through Netcom or telecom fiber or ADSL, and then release information through the external network port of the education bureau.
If the network speed is too slow, first, you can try it on a single machine. Maybe other computers also have ARP. If there is nothing wrong with the stand-alone computer, it means that your intranet is poisonous. Check for drugs.
Second, call the education information network management personnel of the local education bureau. Sometimes it is.
Humans are being adjusted.

Your question has nothing to do with whether you access telecommunications or Netcom. Even your dns has nothing to do with Telecom and Netcom. It is the value given to you by the network center of your metropolitan area network education bureau.
If in doubt, please contact the network center of the local education bureau.
Your school should have their phone number.
