The Canadian IPv6 Summit was held in late April, with an illuminating keynote presentation given by Owen DeLong of Internet backbone provider Hurricane Electric. DeLong’s keynote, titled ‘IPv6 – Light at the End of the Tunnel’ focused, among other issues, on the viability of carrier grade NAT.
He noted that while NAT is the only alternative to IPv6 with any traction, there are very few test implementations and instant messaging and VOIP are severely impaired or non-functional in all implementations.
In addition to these problems with NAT, he cites concern with consumer premises equipment (CPE), describing this as “the biggest remaining gap”, and last-mile telco infrastructure such as DSLAMs and BPON/GPON concentrators.
