I have two devices connected to the same WiFi connection. I have changed the DNS of one domain. When I enter to that domain from device A it works OK, but if I try to enter from device B it does not work.
Device B is a Mac, I try all the available commands to clean the cache;
sudo dscacheutil -flushcache sudo killall -INFO mDNSResponderew sudo killall -HUP mDNSResponder
It still happening the same in the Macbook, although I'm not available to see the DNS change but in the other device.
