What are the different types of memory addresses in a Cocoa application?

Question

Whenever I look at memory addresses in my Cocoa application, I notice (in general) 3 main categories of addresses

• 0x00006xxxxxxx
• 0x00007fffxxxx
• 0x0000001xxxxx

I have an idea of ​​exactly what ... how did I notice that the addresses 0x00006xxxxxxxseem to be pointers to my application objects?

and 0x0000001xxxxx, apparently, are addresses in actual objects in memory?

But I really don’t know anything and cannot form a good Google request to give me an answer.

Does anyone have a resource or know how to identify address categories in a Cocoa application?
