Steps to reproduce the problem:
As web apps are depends so much on domain and HTTPS, It's very handy if we can override domain names to a different IP address (something like hosts file only specific to the browser) at least in chrome canary so we can use canary to access development server and stable to access production server on the same machine with the same domain.

This question has been repeatedly asks in many places:

https://superuser.com/questions/512241/how-to-set-custom-dns-server-for-chrome-browser

There are also some chrome extension which none of them works.

What is the expected behavior?
