Where Did My Office Computer Go? Scan IP ranges for a service

So I lost my computer, since the network MAC->IP cache was flushed, however I know the subnet and the machine is on. But its a headless piece, no monitor. Where oh, where did my computer go??!?!?! Wireshark is more for recording what comes in, other network utils are on a IP basis... but lets curl ourselves out of here... I want to validate the existence of a twiki site:

curl -f -m 2 http://10.10.10.[100-200]/twiki/bin/view

Yeah its that easy.... and easy to forget...
