Steps to reproduce the issue: Freshly installed Docker for Mac version 0.12.0-rc2. Logging in to the quay.io hub server doesn’t work:

$ docker login quay.io
Username (pietv): 
Password: 
Error response from daemon: Get https://quay.io/v1/users/: dial tcp: lookup quay.io on 192.168.65.1:53: read udp 192.168.65.2:37176->192.168.65.1:53: i/o timeout

Pulling public images from quay.io doesn’t work:

$ docker pull quay.io/eris/data
Using default tag: latest
Error response from daemon: Get https://quay.io/v1/_ping: dial tcp: lookup quay.io on 192.168.65.1:53:   read udp 192.168.65.2:44125->192.168.65.1:53: i/o timeout 

(Both operations do work with docker 1.11.2 on Mac.)
