In an earlier article I talked about how to set up a batch script to loop through a range of IP addresses and attempt to resolve active machines within that range. In this article I will follow up on my earlier examples to help make the results of the scan more accurate.

Sometimes you will want to find out more about your local area network and what machines are running at certain IP addresses. Querying the domain name server can be unreliable since some machines may be hidden, so sending a direct ping is the most reliable way of checking for the existence of a machine.
