    The big advantage is that all my computers are reachable through the internet, no more NATting port 80 and port 22 to strange ports because you can use every port only once.
    A secondary advantage is that port 25 is not filtered, although that's not inherent to IPv6, just a lucky benefit of my current tunnel-provider.

    Cisco has nice graphics of the IPv6-deployement in the world. It's based on the same measurements but presented with nice graphs instead of a boring table of numbers. Look up your own country at [] .

    No. That in itself is never a downside. If you don't want rest of the internet connecting to your computer/network, you filter it at your firewall (usually router). Personally I wouldn't mind if it was a requirement that all routers meant for home usage had a factory default that only established/related connections were allowed to LAN side from WAN port(s). Of course that should be configurable, but just sticking the router in would give reasonably secure default.

    In actual fact, the ComCast internet service is not too bad.

    Their cable TV service is another story. I'm reading this article right now because my cable box is busy rebooting...again.

    How do you [Slashdot users] see IPv6 transition actually happening?

    Will each internet user have dual stack?

    Yes. They will have a dual stack with the IPv6 address being used for a bigger and bigger proportion of traffic. Meanwhile IPv4 will probably traverse some NAT.

    Once IPv4 is the minority of traffic (many years in the future), it will turn into a legacy PITA to administer separately. But that is a while away.

    IPv6 is much more complex, how will companies support users who barely understand IP addressing when IPv6 is going to seem like a long string of meaningless characters?

    Those 30% of Comcast customers aren't calling a helpdesk and reading out hexadecimal digits. If DNS is working they will say things like "". If DNS isn't working then they can't fix it by reading out or typing those "meaningless characters".

    Do you see something like a dynamic IPv6 to IPv4 DNS/NAT translator to hide IPv6 complexity from the user a viable solution?

    Not viable. It wouldn't help more than a single digit percentage of users anyway.
