check_icmp with reverse error codes?

Are you aware of any check_icmp type plugins that return the opposite error
codes, so that it returns an OK is there is no reply, and an error if there
is a reply? I want to monitor my unused static IP addresses so I am alerted
if somebody fires up a machine, which would be good for locking down the
address space for better documentation and security. The obvious answer
would be to make the necessary changes in check_icmp, but I'm pretty much
completely new to the coding scene.

Thanks,

Chris
