Vint Cerf Calls For IPv6 Incentives In UK 164
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."

For one, the protocol defined address specifically as 32-bit. Functions processing IPv4 generally use unsigned integers for the address. Functions to do a variable length address would take longer to process/route. The routing tables would likely be atrocious even if it theoretically could work.
In short, it only does better at backwards compatibility at the extremely superficial aspect of entering addresses textually looking more usual and making a more specific effort for an existing IP to map trivially to a new scheme. Existing IPv4 stacks would have had no easier time trying to talk to 192.168.2.250.2 than fd7e:691a:da42::1. Besides, having the high values magically become reserved on the host portion of existing networks would conflict with existing host addresses in use.
IPv6 can work but has been subject to three major pitfals:
-It looks scarily different. People treating addresses like phone-numbers and not doing DNS in a ubiquitous has exacerbated the problem.
-They completely omitted a strategy for v4-only to v6-only communication until this year. For a long time they didn't want to endorse anything with the letters 'NAT' in them and delayed a sane interop strategy hoping the problem would magically disappear so the 'evil' NAT wouldn't become a pillar of v6. I'm optimistic that the results of this year paves the way for meaningful progress.
-v6 and associated protocol largely chose to throw the baby out with the bathwater on many fronts. v6 for a long time declared DHCP dead, then when DHCP was revived for v4, they threw out the existing behavior and started from scratch, eliminating many option codes and changing client identifier behavior to be hard for existing DHCP admins to deal with. This has in some cases rendered workflows in IPv4 simply impossible and in many more exacerbates the first problem in that a *lot* of relearning and reworking is required to acheive the same results with IPv6 as in IPv4.
Running IPv6 in practice (Score:3, Interesting)
I always had a hard time understanding IPv6 until I read the Running IPv6 in practice [debian-adm...ration.org] howto on Debian-administration and tried it at home. The next move is configuring the office where I work to use such a tunnel, then a friend's colo server, then our hosting environment. It's really not hard. Get over the adressing scheme. IPv6 is much easier to manage than NAT.
Tunnelbroker [tunnelbroker.net] by Hurricane-Electric also does a great job of making IPv6 easy to use and fun to learn (the "certification" games). They also throw in free DNS hosting, and announcing IPv6 addresses using BGP is possible.
Now stop whining and bite the bullet :-)
