Description of problem: The 'oc' cli tool will not function when the system is using OpenDNS (208.67.222.222). When using Google's DNS server (8.8.8.8) it functions as expected on Mac OS X 10.12 Version-Release number of selected component (if applicable): How reproducible: Every time Steps to Reproduce: Use OpenDNS instead of Google's DNS server
$ oc version oc v3.1.1.6 kubernetes v1.1.0-origin-1107-g4c8e6f4 $ uname -a Darwin Galactica.local 16.1.0 Darwin Kernel Version 16.1.0: Thu Oct 13 21:26:57 PDT 2016; root:xnu-3789.21.3~60/RELEASE_X86_64 x86_64
Can you confirm this is a Mac OS X only issue? I wasn't able to reproduce it on Fedora, not even trying to force cgo to DNS resolution, as specified in Go's Name Resolution[1] topic: GODEBUG=netdns=go+2 oc login https://api.tsi.openshift.com/ GODEBUG=netdns=cgo+2 oc login https://api.tsi.openshift.com/ Both succeeded. Also, your nslookup command prints 10.0.0.1 as the server, can you confirm it's correctly using OpenDNS (208.67.222.222)? [1] https://golang.org/pkg/net/#hdr-Name_Resolution

Yes, definitely looks like the same issue. Adding Clayton and Derek.
We're still depending on a Go fix here https://github.com/golang/go/issues/12524 https://github.com/golang/go/issues/16345
I see the customer case is closed for a while, I'm closing this BZ as well. Feel free to re-open if the issues still exists.
