I use Advanced IP Scanner.The number of details provided by the Advanced IP Scanner are the most appropriate and accurate. On the basis of my experience, I can bet that this tool, so far is the best utility available for IP scanning. The best part being the scanning of the WiFis.

This is a handy little piece of software. It is extremely helpful to find what is on your network. Best of all its free. Famatech has upgraded its free network scanning tool Advanced IP Scanner to version 2.4.2601
