Well, somewhere in 2000::/3, anyway… It might be somewhere within any of the following blocks: 2001:400::/23, 2001:1800::/23, 2001:4800::/23, 2600::/12, or 2610::/23, 2620::/23.

All of which have been delegated to ARIN by IANA.

As to the PI/PA question… There were PI blocks issued by LIRs (ISPs) in the years after the initial implementation of CIDR and before (and possibly for some time after) the creation of ARIN. My blocks 192.159.10.0/24 and 192.124.40.0/23 are examples of such blocks which were originally issued to me by Netcom and PSI, respectively. They are now correctly documented as "Direct Assignments" in the ARIN database and covered by LRSA (which I now regret given the recent fee restructuring).
