Overlook Fing is a neat and straightforward tool for running network IP address and service port scans. It's fast, it provides a lot of information, and you can email the scan results directly from the app. One of the other great things about Overlook Fing is it is a cross-platform product with sibling versions (also free) for Windows, OS X, and Linux. Overlook Fing gets a rating of 5 out of 5.
