A new traffic analysis by Arbor Networks suggests the next-generation Internet protocol could finally be trickling into use as carriers gain the confidence to use it in its native mode. The dominant use appears to be for P2P, particularly uTorrent, a file-sharing system whose users have adopted IPv6 as a way of hiding from ISPs. Arbor takes this to be a positive sign that carriers are finally abandoning the hugely inefficient practice of burying or tunneling IPv6 packets inside IPv4 ones.”]
