sweetpea23 writes "Vint Cerf, the 'godfather' of the web and Internet evangelist for Google, has highlighted the need for cash incentives to encourage ISPs and businesses in the UK to move to version six of the IP addressing scheme (IPv6). In response to the UK government's stance that its role in the transition will primarily be advisory, Cerf suggested a system of tax credits for upgrading equipment to v6 capability — similar to the 'cash for clunkers' scheme in the US. 'You'd have to do the math to see what impact it would have, but creating some business incentive might be helpful,' he said. His words echo those of Axel Pawlik, managing director of the RIPE NCC, who warned last month that that the IT industry is adding unnecessary risk and complexity to Internet architectures by ignoring the availability of IPv6 addresses. the Internet authority IANA is expected to assign its last batch of IPv4 addresses in June 2011."
