Ah, finally: the truth is there:
From the page No business case for IPv6, survey finds - Network World:
No business case for IPv6, survey finds
Business incentives are completely lacking today for upgrading to IPv6, the next generation Internet protocol, according to a survey of network operators conducted by the Internet Society (ISOC).
In a new report, ISOC says that ISPs, enterprises and network equipment vendors report that there are ``no concrete business drivers for IPv6.''
However, survey respondents said customer demand for IPv6 is on the rise and that they are planning or deploying IPv6 because they feel it is the next major development in the evolution of the Internet.
Yeah, right: "planning IPv6".
