"You also stop more of the finger pointing, where the ISPs claim there is no need, because there is no content, and the content providers claim there is no one using it, therefore no need to provide content."

"Unfortunately with the transition taking as long as it is we are stuck with NAT [network address translation] and will be for some time," Clark said.

NAT is a process whereby IP address information of IP traffic is modified while in transit. "With NAT you get extra latency (ie delays in content delivery), mismatching of flows, more dropped flows, and more traffic unable to be set up in the first place. That means: missed pages, missed calls, and missed business/education/communication," she said.

"Another issue with wider and wider implementation of NAT is that it provides a distorted network model -- tromboning everyone's traffic through NAT boxes rather than over more optimum paths," Clark said. "This results in more delay and bandwidth inefficiencies--congestion where you don't need it."

IPv6 provides about 340 trillion IP addresses, compared to 4 billion addresses under IPv4. Exhaustion of IPv4 addresses has necessitated the transition. When it came to IPv6 adoption, and many Asian countries going into World IPv6 Day this past June.
