ipv6 is working just fine even here at IETF49 venue, it's so much more
convenient than IPv4, for couple of reasons.
We can't use IPv6 until multihoming issues are properly solved
and global routing table size and the number of ASes are
controlled to be below reasonable upper bound.
If I am reading this right you want a upper bound for routing table size?
Well,considering the problems some operators have to aggreagate maybe that
would be a good idea...:)
