UK ISPs Respond To the Dangers of Using Carrier Grade NAT Instead of IPv6 165
Mark.JUK writes "Several major Internet Service Providers in the United Kingdom, including BSkyB, Virgin Media, TalkTalk, AAISP and Fluidata, have warned that the adoption of Carrier Grade NAT (IPv4 address sharing) is likely to become increasingly common in the future. But the technology, which many view as a delaying tactic until IPv6 becomes more common place, is not without its problems and could cause a number of popular services to fail (e.g. XBox Live, PlayStation Network, FTP hosting etc.). The prospect of a new style of two tier internet could be just around the corner."
A few of the ISPs gave the usual marketing department answers, but three of them noted that they've been offering IPv6 for ages and CGNAT is only inevitable for folks that didn't prepare for what they knew was coming. Which, unfortunately, appears to be most of the major UK ISPs.
Major Supplier does not want home based servers (Score:2, Interesting)
I've been following the IP6 thing here in the UK with interest. BT the major supplier seem to be uninterested in full IPV6 for all customers. I've seen statements that they are pursuing CGNAT for IPV6. If this is true it beggars belief. The only reason I can that makes any form of sense is the attempt to stop a proliferation of home based servers, suck as toasters, fridges, TV & PVRs etc.

In the early day of the internet we didn't even bother with DHCP, all the PCs in the lab had static internet IPs.
Linux and windows 95 with static internet IP4 address with no firewalls.
Pull something like that now and you are fucked up in 2 minutes. :)
IPv6 core, IPv4 edge, thanks vendors (Score:4, Interesting)
the big providers in the US, and many of the rest, are IPv6 enabled in the core. but edge equipment at the subscriber is not up to the task, so NAT IPv4 is how it's done here. virtually all of the DSL modems are MD'd (manufacturer discontinued) IPv4, so it makes sense.
