NetCheck is a Free, simple Internet Connection Tester. It can be used to "check the status of your internet connection" by attempting DNS resolve and TCP connection tests. The DNS test allows NetCheck to test if your system can currently resolve Internet addresses to their respective numeric IP addresses, and the TCP test determines if your system is able to connect to servers on the Internet. Just launch NetCheck and press the Start button to run the test.
