Noah, you can't use that argument. Perhaps a better number to look at
would be how many ASN's there are in the routing table, and how many of
them are IPv4 only vs how many have both IPv4 and IPv6 or even IPv6 only.
Most ISP's run with one ASN but many run with multiple ASN's - but I
believe ASN's would be a better measurement.
I, as an ISP advertise one /32 of IPv6, and multiple IPv4 prefixes.

Occasionally at AFRINIC Meetings, we have an "IPv6 only" day. Generally,
most people survive just fine. I think this "IPv6 Only" day event should
perhaps be something we always do at our meetings. Its also been done at
SAFNOG (Southern African NOG) a few times.
