Yosemite offline DNS resolver bug: resolved as of 10.10.4 (14E26a)
As of Yosemite you can no longer resolve DNS when you are not connected to a network, this prohibits you from running a local DNS server with wildcard DNS to do development when you are on a plane or train without an Internet connection or trying to present to a client where you don’t have wifi access. So the response from Apple is that is expected behavior, and the applecare contact suggested I use the hack proposed at http://arstechnica.com/apple/2015/01/why-dns-in-os-x-10-10-is-broken-and-what-you-can-do-to-fix-it/ (which I sent to them) At this stage he doesn't know if it will ever get fixed.. no indication from engineering..
