How to redirect traffic to one IP to a different IP on Windows Server 2008

I've just migrated to a new server but some of the legacy code has some IPs hardcoded. Can someone tell me how to redirect requests for one IP and make them go to another?

EG. I ping 83.83.83.83 and it gets redirected to 66.221.24.31.

I'm using Windows Server 2008
