Ban URL from IPs

[Lastwords]

How would I ban www.domain.com/something from a particular IP address (s). I would want the user to see the rest of the website (ie www.domain.com). Would I need to redirect? Mod_Rewrite?

Thanks

The "from a particular IP address" requirement makes it a job for mod_access or mod_rewrite.
