I'm trying to map 'localhost' to an IP address elsewhere on the network, say '10.0.1.1' for example. I've tried editing my hosts file, changing the entry from: 127.0.0.1 localhost to 10.0.1.1 localhost with no luck. The closest I've gotten is using DNS spoofing via Charles. Adding a DNS spoof entry mapping the host name 'localhost' to '10.0.1.1' works fine in Firefox, but fails in Internet Explorer, basically showing IE's 404 page. I'm wondering if there's some specific setting or way I can get DNS spoofing to work in IE? The main issue I'm trying to resolve is that our development environment points to 'localhost' and rather than setting the dev env up in a legacy Windows laptop to try and debug, point to a server that has it all setup and I can make the changes remotely.
