I find it interesting that no operators are screaming that there will be too many routes, but that all the IPv6 researchers are bringing forth this view.
ACK. All the "oh our IPv4 DFZ table explodes today" is similarily unfounded as far as I'm aware. I have not heard of anybody being able to crystal-ball the scaling limits of BGP4 yet, and currently used BGP implementations seem to cope quite well with 150k routes (set aside the notorious vendor C artificial RAM limits in older gear to make you buy new gear when table gets bigger).
8 years too late guys. We've figured out table management.
ACK, looks like that. And even if all active ASses would immediately adopt IPv6, we would land at about 18k IPv6 routes. "big deal". And I don't see multihoming adoption in IPv6 being anywhere quicker than in IPv4, so: where is the problem, please? We'll have about 1 route per ASN... so even when exhausting the 16bit ASN space, this will be only <65k routes. And when will this be, extrapolating active ASN growth? 2010? 2015? Call me a retarded idiot, but I have a really hard time seeing any _practicle_ problem with "1 ASN == 1 IPv6 prefix" at all.
