How to edit hosts file :Windows xp/vista/7/8 Ubuntu Mac

Hosts file is something like a directory service. It maps ip address with the corresponding websites. As the incorrect phone number entry against a name puts your call to the wrong person, similarly a incorrect ip address entry against a website will land you on wrong website.

Thus when you manipulate this hosts file entry you can redirect users to different website or simply a non existing ip address.

You will need to remove the Read Only parameter of the hosts file first. You can do this by right clicking the file -> properties -> uncheck read-only attribute.
