[AccessD] Ping IP

John:

Does this description sound what you need?

Ping a range of IP numbers to find out what numbers are in use, or what
numbers answer within the set time. Use it to find out what parts of your
network are slower then others and maybe you even need to take a closer look
at them. Adjustable time out, bytes to send, start and end node. Save the
results of the sweep as csv and import them into a database.

If so, go to

Free as far as I can tell.  Haven't used it.
