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.


You can temporarily try to change the DNS Servers on your Mac to use the Google Public DNS or Open DNS to see if is a problem with the DNS of your provider.

  • recently I change my ISP, and I was using an old router DNS address thank you! – user222601 May 8 '13 at 12:10
