From the second source: "If all these unused ASNs could be recovered, the pool of ASNs would last until 2025 to 2030." So, if we think that 2^32 is ultimately unobtainable, we're just facing a deadline with 2^32's being the "norm" per AS of a few years longer. Of course, this doesn't even answer the question of how to get from 2^18 currently, to 2^32 in the first place. :-) Russ - -- riw@cisco.com CCIE <>< Grace Alone -----BEGIN PGP SIGNATURE----- Version: PGP Desktop 9.0.2 (Build 2424) iQA/AwUBQ2t4+xEdu7FIVPTkEQIGUACfXDFqrwMY08f2ow+YeyafOoIVSG8AnRp0 hPXzjJt87XUCJ1mrfSDJr9o+ =ZRk5 -----END PGP SIGNATURE-----
