The ICSI Netalyzr
Posted by blackvelvetjesus in the wired 8 years ago
The Netalyzr analyzes various properties of your Internet connection that you should care about — including blocking of important services, HTTP caching behavior and proxy correctness, your DNS server's resilience to abuse, NAT detection, as well as latency & bandwidth measurements — and reports its findings in a detailed report. You can check out an example report from a real network to get a better idea of our tests.  
 
To perform these tests, the Netalyzr runs a Java applet on your computer. You may be asked to confirm network-related activities that your system's applet security policy or firewall considers sensitive. We hope that you will permit any such activity, as it will ensure more comprehensive test results.

XIV: I have used this on everything in my home network, and as a tech-minded individual who's too lazy to tear shzt up and figure out what's wrong, this is a REALLY good tool to just open on a browser and check things out.
