How do i change the Host File Information

In Windows XP the host file information is setup in the following path by default
c:\windows\system32\drivers\etc\host

You can edit this file using the note pad and can give the IP names and the host header information there so that it redirects you to the remote sites that are hosted by the servers.

for instance i had the following requirement
156.81.248.28 http://testwip.mycompany.pvt/

If you add this host information in your host file it will redirect you to that location.
