Notwork

Notwork is a network connection diagnosis tool, that performs four standard network tests for you.

The app is geared towards Network Administrators who can't be bothered to manually "ping", "dig" and "curl"! 

It automates the standard procedure to diagnose a network almost completely!

So, in order to check your connection, Notwork:

1) Verifies your IP and Subnet, making sure that the IP is valid and not a link-local IP, and that it's in the range allowed by the Subnet) and alerts you of any problems it finds.

2) Pings your default gateway (your router) making sure that the device is running.

3) Checks your DNS servers and makes sure they are fully-functional (by querying them for apple.com)

4) Attempts to connect to popular sites like Google, Apple, Twitter and Facebook.

And Notwork does all this, while also keeping your data private. NO data is ever transmitted, every Network check is done on your iPhone only.
