    So now we know what Gareth gets up to in his spare time, he counts grains of sand. ;)
    Although maybe his spaceship could be put to better use. :D

    lol

    it be interesting how transparent that ipv6 will be when it is switched on as it can be bad when a ISP does not correctly handle the routing of IPV6 or websites just dont work

    NAT isn't just a nuisance. It's actually a great way to separate internal networks from the Internet. With IPv6 this is much harder to accomplish.

    They're talking about ISP NAT, like on 3G networks where they give devices a local address on the WAN to conserve public IP addresses

    It's not exactly the end of NAT either, or is it the end of separating internal networks from the internet.

    Almost all home routers actually have a firewall with a default deny inbound as well as NAT preventing routable subnets being behind the router. So merely switching to IPv6 with NAT disabled, and a routable subnet, doesn't inherently imply that you'll have less security, as your firewall will still be there.

    Also, there's still non-routable local link addresses (e.g. the IPv6 equivalent to 192.168.x.x) available as detailed under http://tools.ietf.org/html/rfc4193 - which will require overload NATv6 on the firewall.

    you still have internal and external addresses, so could still set an ipv6 nat as zoon said

    I was sort of into IPv6 at first, but then realized it makes it damn hard to block IP's of those you wish to block, there's too many of them and you need new utilities too.
    One way I noticed was that I had something blocked and I still landed on the blocked site, turns out windows automatically fell back to using the IPv6 address when IPv4 failed. Go figure.

    (or is it 'fell forwards'?)
