ping a subnet ?

[Polaris]

Hi:

I know the "ping" can be used to test a particular host's response given the
host's IP or DNS name.

Just wondering if there is a way to test if ANY host of a subnet is
responding without looping through all possible hosts?
For example, for subnet 1.2.3.xxx; is there a way to test if any of its
host is responding?

Thanks in advance!
Polaris

Wow! What a neat little tool! A sensible interface, and a set of options
that are really useful.

Thanks for the pointer.

Try IcmpSendEcho[2] with the subnet's broadcast address.

Just make sure you "exclude" it from any/all of your anti-spyware utilities.
For some reason, most label it as spyware and may remove it automatically.
