Next up, Advanced IP Scanner.

If you're on and you find that you often need to survey your TCP/IP-based network to find out what devices are running, the latest version of Advanced IP Scanner published by (purveyors of the fine remote access utility Radmin) is a must-have.

is a free tool that allows you to scan an IP address range. It's very fast and you can choose whether to show "alive" and/or "dead" addresses, the device manufacturer's name, the device MAC address, the current user (if available), the associated DNS name and, optionally, the NetBIOS names and groups the device uses. It can also scan for shared folders, HTTP and HTTPS, and FTP services and Radmin availability and can save scan results.

Advanced IP Scanner is incredibly useful and gets a Gearhead rating of 5 out of 5.
