I noticed Mavericks prefers the DNS server to /etc/hosts (scutil --dns). There used to be a good 'ol "order hosts,bind". Is there anything equivalent for Mavericks so my hosts file is consulted before reaching out to the DNS server? Thanks.

    Please elaborate your thoughts about lookup order changes and add some examples. On my system the order is hosts->mDNS->DNS (except using dig, host and nslookup of course) – klanomath Feb 24 '15 at 20:34

(Cross-posting my Reddit answer here.) In my experience, it's more of an additional priority issue: IPv6. It hit me in Mavericks, but probably dates back to Lion. I develop on my local machine using /etc/hosts aliases to route requests through nginx, but on slow Wifi with slow DNS, it will often hit a 5-second timeout before bailing out on IPv6 and trying IPv4, realizing that there's a relevant /etc/hosts entry, and resolving that way. Not very convenient to have +5s tacked onto my recode-reload cycle.

Adding a ::1 example.com line to go along with my 127.0.0.1 example.com lines resolved the issue for me.

I've noticed this dns authority priority inversion in 10.10.2 (Yosemite) but not back in Mavericks.

I just started this thread. https://www.reddit.com/r/mac/comments/2y22sj/yosemite_ignoring_localhost_etchosts_redirects/
