I was in Apple Store the other day. My computer wasn’t able to access their WiFi, as I was using Google’s DNS servers. After I took out the 8.8.8.8 and 8.8.4.4 resolvers by Google DNS the internet was accessible again. The Apple Store employee referenced that Apple has their own DNS servers for all computers in their stores. He stated that he used it on his own personal computers, too. Does anyone know what Apple’s own, internal DNS servers are?
