Using dnsmasq when not connected to the Internet I'm routing dns requests through dnsmasq so that domains I'm using for local development point to 127.0.0.1. This works great when I'm connected to the Internet via Wi-Fi or ethernet, but I start to have problems when I'm not connected to the Internet at all.

In dnsmasq.conf, I have this setting:

address=/gentoo/127.0.0.1


Turning off all network connections, I run:

$ dscacheutil -q host -a name test.gentoo
name: test.gentoo
ip_address: 127.0.0.1

$ ping test.gentoo
PING test.gentoo (127.0.0.1): 56 data bytes

64 bytes from 127.0.0.1: icmp_seq=2 ttl=64 time=0.177 ms

3 packets transmitted, 3 packets received, 0.0% packet loss
round-trip min/avg/max/stddev = 0.043/0.109/0.177/0.055 ms


So that seems to be working fine. But if I try to open http://test.gentoo/ in Chrome, I get the message:


  Unable to connect to the Internet Google Chrome can't display the
  webpage because your computer isn't connected to the Internet. 
  
  You can try to diagnose the problem by taking the following steps: 
  
  Go to Applications > System Preferences > Network > Assist me to test
  your connection. Error 106 (net::ERR_INTERNET_DISCONNECTED): The
  Internet connection has been lost.


Chrome sees that I don't have a network connection, and it doesn't even try to make the request.

Any idea how I can work around this? Can I create a dummy network interface to convince Chrome I'm connected to the Internet? Can I make it send the requests even though I'm not connected? Any other ideas?

I tried the solution at https://serverfault.com/q/22419/92378 but it did not work, as I'm on OS X 10.7.3, so resolver is ignored when not connected to a network.
The solution on https://serverfault.com/q/22419/92378 is working for me (OS X 10.9.4). Just make sure to do this step:

Create a file /etc/resolver/whatever:

nameserver 127.0.0.1
domain .
