[X4U] OSX net tool?

[Craig A. Finseth]

	...
   Looking for an inexpensive utility that can list all the IP addresses 
   on a LAN. I am a casual tech support guy for local friends and 
   businesses and sometimes I need all the addresses on a net - without 
   manually cruising around to get them... including IP printers, etc.

I assume that you mean "in active use by machines that are turned on."

Did you try NetUtil?
