While browsing and using the web, DNS stops working. Open web-chats like Google Hangouts keep working, but opening new websites, Skype, and others are stuck to "Resolving host name".

This happens randomly, sometimes when I return from sleep mode, others when I switch from WiFi to ETH, others just while doing nothing in particular. I tried things suggested in DNS not resolving on Mac OS X without any success.

Moreover, I can resolve the problem if I reboot the Mac entirely, but I want to figure out 1) why its happening and 2) how to fix it once and for all!

  • I'm running 10.11.1 (15B42)
  • I'm on a home network, my ISP is Kabel Deutchland
  • My router doesn't accept "custom" DNS servers and I can only change them in every client.
  • I am using Google DNS servers since sometime while trying to solve the problem.
  • Comments are not for extended discussion; this conversation has been moved to chat. – bmike Nov 4 '15 at 1:04
