How do you reroute a domain name to a different IP address?

[helppls]

Windows 7. I need www.whatever.com to reroute to 123.123.123.123 in all Internet applications.


I know how to do this with the hosts file, but I need something easily reversible (something I can put in a batch file, for instance) without requiring a restart.

Make a second copy of the HOSTS file with the settings you want, then make a batch file to rename/swap the two files as needed.

Use DNS, like you're supposed to do.

Why do you want to do this?

One thing you can do is use opendns, and program it to block a site.
Then when you need to use the site change the dns to google's dns.

So many ways to do what you want but I would like to know why and that will help us give you the appropriate answer.
