So lets just take a rough guess and That is because once an ASN is allocated it almost never is recovered by the 3 RIRs (RIPE is probably the best organized of the 3 and it never gets around to reclaiming "dead" IP address space as well). I have revoked quite a few ASNs: http://www.isoc.org.il/ipolicy.html but it involves quarterly checking at major NAPs, emails to the contacts, finding new contacts, registered postal letters and plenty of followup. Most LIRs just don't bother since reclaiming a "dead" ASN is a non-revenue affair. > say the number of people who could benefit from having a single region to > get /24s is around 5000, perhaps lower. > > Richard A Steenbergen <[email protected]> http://www.e-gerbil.net/ras > PGP Key ID: 0x138EA177(67 29 D7 BC E8 18 3E DAB2 46 B3 D8 14 36 FE B6) > Hank Nussbacher
