Hi Mohacsi Here is the statistic for PI (assignment) vs PA (allocation) for APNIC region. If you need more information please let us know. Year Number of PI Number of PA 2000 23 354 2001 36 337 2002 44 282 2003 62 368 2004 68 478 2005 118 576 2006 103 727 2007 49 244 We don't have the PI policy until 2000.

P.S.: Anyone got any recent numbers about the percentage of PI announcements in the table vs. PA announcements + deaggregates?
that's probably not the fully adequate answer, but I considered the info in the following two slides (page 9 and 10) as very interesting in this context:
http://www.ripe.net/ripe/meetings/ripe-54/presentations/RIPE_NCC_Statistics....
The bottom line is that the # of PI assignments has (considerably) surpassed the number of PA assignments since 2003, and that the load on the routing table for PI is thus bigger than for PA, although the *percentage* of PI space as compared to PA is approx. 2%.
Or, the other way 'round, we use more than 50% of (additional) routing table slots for some 2% of address space (PI) and less than 50% for some 98% of PA.
Are there similar statistics in the other RIR area? If the picture is similar we have in RIPE region, then we have think over PI address policy....
Only my 2 cents....
