Well, the purpose is basically for the hosting transfer.
I have a friend...
Somebody did a web page hosting for her.
Now she wants to transfer the hosting to have it under her control.
To transfer the hosting, the new provider asks for the DNS.
If she asks the person who has the current hosting, he probably (she thinks) would not be willing to give it up.
She would like to be able to do the transfer regardless of his consent, because it is her name and her web.
