World IPv6 Decade is nearly over...

Oh, sorry, world IPv6 DAY. Some of us have been doing this over 9 years so you understand the confusion.

Seems to be the non-event we all wanted.

Stuff worked.

From what I can see there are various ways that some of the people testing things have ballsed up DNS slightly for the odd moment, or done IPv6 on IPv4 DNS servers (which is fine) or managed to mess up glue records a tad, but nothing that actually shows any issues with the concept - and that is what is important.

For us, I cannot even say that traffic levels are noticeably higher on IPv6 today. It is a tad spiky but often 10% of our LINX traffic (where all the IPv6 seems to go). May be more obvious this evening when residential use hits facebook on IPv6.

It was also, briefly, World blame IPv6 day this morning until we stamped on it. Every problem was "could that be because they have IPv6", even one of general (LCP monitored) packet loss. Soon sorted. They know better now :-)


  1. I would like to say that we did infact manage to join the IPv6 megaconference: http://www.oar.net/press/events/worldipv6day/ Over AA 3G with IPv6 and a videophone, from the pub. albeit for a total of around 20 seconds when the packet loss on the 3G effected the stream too much, however, that would have happened on IP4, too. We really only did this "Because we can" :-)

  2. Aha! SET unlockIPv6 "1"

    Bizarre.. why lock it in the first place.

  3. The Inquirer is claiming a fairly novel reason to go IPv6 - little or no adverts. See http://www.theinquirer.net/inquirer/news/2078219/ipv6-blocking-software-claims-ip-geolocation-firm

  4. correct me if I wrong but
    IPv6 is a disaster for privacy since every household will get a COMPLETE /64 sub net! That means that your devices will be traceable over extended periods of time!

    The Privacy Extensions don't help because they only randomize the last 64 bit but NOT the first 64 bit of any given IPv6 address.

    IPv6 is a privacy disaster!

  5. Err, WTF?

    1. The design of IP, over 30 years ago, is that every device has a pretty permanent unique IP address. IPv6 does not change that. The whois data for IPv4s are meant to record the contact details for every IP even.

    2. As you say, the /64 is irrelevant if you install machines in paranoid mode (privacy address) so the same as having one fixed IPv4. Note that *all* A&A customers have a fixed IPv4 addresses, and always have. People pay extra for that!

    3. Any ISP could, if they were particularly strange, allocate a /64 using DHCPv6 in a dynamic way every time your router connects in much the same way as some ISPs allocate an IPv4 PPP link address dynamically. IPv6 allows exactly the same flexibility as IPv4 for that.

    4. In fact DHCPv6 allows an ISP to make the /64 dynamic even without reconnecting by setting timeouts for re-assignment and using push type DHCP updates to the router, changing IPs of all your machines randomly. IPv4 did not allow that.

    Nothing in IPv6 makes things better or worse for privacy. What is odd is that people think an IP address should not be traceable. I'll expect people to demand dynamic postcodes from royal mail next.

    Privacy addressing is a pain for some people that actually want their machines to stay on the same IP address!
