What if my ISP just routes my /48? Seems to work quite well, actually.
Unlike IPv4 with natural boundary of /24, routing table explosion of IPv6 is a serious scalability problem.
Do you have any *realistic* and *actual* reason to suspect that the IPv6 routing table will "explode" any further than the IPv4 has already? Hint - Owen's /48 will just get aggregated and announced just like the cable companies *already* aggregate all those /20s of customer /32s. Unless Owen multihomes - at which point he's a new entry in the v6 routing tables - but *also* almost certainly a new entry in the v4 routing table. Routing table size depends on the number of AS's, not the amount of address space the routes cover.
