DNS cache in iOS

Hi There,

Is anyone aware of a way to view the DNS cache in iOS through XCode or using other developer tools provided by Apple or via a 3rd party?

The reason is that I am involved in moving the hosting environment for an app - where the app calls it's API's.

Now we will have to move one or more DNS records around, and it is speculated that iOS ignores a DNS record TTL, and sets a hard lock of 12 hours - confirmation needed.

Is there any documentation around how iOS handles DNS caching or DNS in general?

Any help would be appreciated, thanks in advance.

Kind regards, Antonio
