Fiddler shows DNS Lookup failure

On my desktop I run Visual studio web server cassini and fiddler as a proxy, then I connect to a web site running in Cassini using an iPad connected via wireless.

This has always worked since I installed and unistalled the MVC pack for visual studio.

Now I get this message from fiddler (it is sent to the iPad):

[Fiddler] DNS Lookup for "http://175.33.22.116" failed. The requested name is valid, but no data of the requested type was found

There are similar posts with this message, but none of them with my setup.

Can you suggest what to check?

Thank you

This indicates that the traffic from your IPAD client is malformed. Are you using anything in Fiddler (e.g. Tools > HOSTS) to change the traffic? If not, the bug is on the client; e.g. something is trying to connect to http://http://175.33.22.116 which isn't legal (due to the double http:// within the string).
