Where is the Apple documentation about the new Whatnet network?

I added again the screen capture explaining the strangely named interface.

Special note to the moderator

Since there is no personnal information in my screen capture,

there is no need to remove it. In the other case I would have been able to mask it.

For example:

172.20.10.5

is a private IP address which is reserved for private network you might find used everywhere

at any home or mobile network.

I appreciated you took care of this potential private information leak.

I am sorry but this is the name of an interface created by MacOS and the name wasn't asked to me.

This is in no way related to IRC or anything else falling from Google searches.

Thank you for your really funny answer 🤣.

Let's hope your answer won't kill any other good will to answer.

@BDAqua, thank you for your help.

This document doesn't mention any interface named "Whatnet".

But with the activation of "Personal Hotspot" on my iPhone, I have been able to

make appear again this strangely named interface.

I am progressing to understand this undocumented "feature".
