macOS 10.12.1 (16B2555) on an early 2015 Macbook Pro.
I can't resolve any
.io domains on this machine. Other people on the same network can. This happens here at the office, and at home.
I've tried different browsers, I've turned it off and on again.
[~]$ nslookup ngrok.io Server: 10.15.0.1 Address: 10.15.0.1#53 Non-authoritative answer: Name: ngrok.io Address: 220.127.116.11 Name: ngrok.io Address: 18.104.22.168 Name: ngrok.io Address: 22.214.171.124 [~]$ ping ngrok.io ping: cannot resolve ngrok.io: Unknown host
If I add the domain manually to
/etc/hosts, and then run a traceroute, I don't see anything abnormal. I'm able to bring up the domain in a browser.
Definitely seems like a DNS issue, however, I'm not using DNS settings that are any different from anyone else on either my home or work network.
If I change the DNS servers manually to
126.96.36.199, it STILL does not work.
