I wanted to create an app which will access data across site collections so I downloaded code sample from here.

I published this VS solution so I got app package in solution BIN folder. I uploaded that app on my app catalog site and then add this app in same app catalog site so it's showing in "Site contents".

I clicked on the app which redirected me to app site but I didn't see it, instead I got below error on the page

[Fiddler] DNS Lookup for "app-1be620271cad00.spapp" failed. System.Net.Sockets.SocketException The requested name is valid, but no data of the requested type was found

BTW Fiddler is installed on my DEV machine.

This error is saying something about the DNS settings so I googled and found below articles which says I need to setup some DNS related stuff, but how can I do this?

I don't have any DNS Manager on my DEV machine? Is there any other way to solve this?
