[arin-ppml] Revealing /32 customers?

I work with several ISPs, and to my knowledge, none of them have ever been asked to provide any more information than what is already in SWIP/WHOIS, which would mean only /29 and shorter. In fact, I don't think they have ever been asked anything at all. I just assumed that since the SWIP/WHOIS data was already there, it was being used.

In many cases I have seen "/24 allocated as /32 static assignments to customers" be sufficient justification.
