Changing DNS - Cloudflare 1.1.1.1 and Drexel DNS

Drexel DNS

144.118.27.33 and 144.118.27.50 are the DNS addresses for Drexel.  But letting your computer automatically detect this is usually best for on-campus network resources.

Refer to the directions above to change the DNS on your MacOS or Windows machine.

Do this on machines that stay on Drexel campus only.
