I have an incorrect asset_host, but can't change it

In the console, development mode:

ActionController::Base.asset_host 

=> 192.168.2.55 

which happens to be a previous DHCP address.

I checked:

RAILS_ROOT/config/environments/development.rb

RAILS_ROOT/config/environment.rb

... and there is nothing set here. Even if I add

config.action_controller.asset_host = "http://12开发者_StackOverflow社区7.0.0.1"

to development.rb, I get the old DHCP address. I've tried clearing browser caches, name server caches, but am out of ideas.

The culprit is RAILS_ROOT/config/facebooker.yml
