Of course most of us punch it manually as loopback0 IPv4 to have more control over outcome. Question is legitimate and represents change where previously used mechanisms do not apply, therefore OP is right to ask 'well what should I do now'.
I'm not used to punching anything, so I probably have too simple a view of the world. But I still don't understand how this changes the ID allocation scheme, which is how I understood the question. I assume the punched value was based on input from somewhere? Bjørn
