Are there P2P applications that prefer v6 over v4? or only work on v6? If a host has v6 capabilities, in my experience, it'll use them atleast as often as v4 when given the chance.
These estimates seem way high and need support. Here is a counter-example. Netflow on Internet 2 for last week http://netflow.internet2.edu/weekly/20050829/ has 6.299 Gigabytes being sent by IPv6, out of a total 383.2 Terabytes, or 0.0016% This is backbone traffic, and would not catch intra-Campus traffic, nor would it catch tunnel or VPN traffic, but it is suggestive. By contrast, (IPv4) UDP is 12 % of the data sent, and (IPv4 ASM) Multicast is 1.76%, so IPv6 trafic is just about 10^-3 of the Multicast (before any fan-out). According to the graph http://netflow.internet2.edu/weekly/longit/perc-protocols41-octets.png the most I2 IPv6 traffic was in 2002, when it was almost 0.6% of the total. It is hard for me to imagine that the situation for commerical US traffic is much different. There may be similar statistics for Geant - I would be interested to see them. Regards Marshall Eubanks
I think the last v6 traffic study I saw still said +90% of the v6 traffic was still ping/traceroute :(
