Well, my example was for a /16 (not the /14, which comes with another 
story), currently announced by the LIR as /16 and partially as /17, with
6 smaller ranges announced by another entity of this LIR and 23 PIs
announced out of 38 (so much for "accuracy" ...) by other ASes.

Breaking up the /16 into PIs and PAs would end up with 42 new prefixes
in the routing table (beside the current 3+6+38 seen ones). OTOH, at
least the 23 announced prefixes would become PIs as the others (50€
for the LIR or a direct agreement with RIPE) and the remaining 15 PIs
would be either returned or registered as the rest.


@Ingrid:
Have you made an analysis, how many new prefixes would show up in the
routing table by de-aggregation the A-PI/A-U allocations (best case/
worst case), how many of the PIs in there are currently seen (or not)
as separate announcement? Just to get a feeling ... (yes, everyone
can do this, but everyone is busy ... ;-).
