Facebook Engineering, on WIPv6D:

""" World IPv6 Day came to an end earlier today. We successfully enabled IPv6 on our site for 24 hours, with great results. We saw over 1 million users reach us over IPv6. We’re pleased that we did not see any increase in the number of users seeking help from our Help Center. The estimated 0.03% of users who may have been affected would have experienced slow page loads during the test. Based on the encouraging results, we’ve decided to leave our Developer site dual-stacked, supporting both IPv4 and IPv6. And we will continue to adapt our entire code base and tools to support IPv6. We are glad to have joined with the Internet Society, major Web companies, and other industry players to enable IPv6 for this test day. It was a great opportunity to test our infrastructure and IPv6 readiness. IPv6 is vital to the continued growth of the Internet, and World IPv6 Day was a great step in the advancement of the protocol. We hope the overall success of the 24 hour test will encourage others in the industry to establish reliable IPv6 connectivity and develop robust IPv6 products. Donn is glad the Internet didn't break today. """ That last was in italics... :-) Cheers, -- jra -- Jay R.

World of Warcraft may begin using IPv6 on Tuesday
by Kevin Day 09 Jun '11

09 Jun '11

For those that don't know, World of Warcraft is currently the largest online role playing game, with somewhere over 12 million subscribers. Version 4.1 of the game is expected to be released this Tuesday, which will be automatically pushed to all clients. The current Beta version of 4.1 has full IPv6 support. In the beta, it's automatically enabled if you have native IPv6 (non-6to4, non-Teredo). While Blizzard has been pretty silent about this, barring a last minute revert or delay of this patch, there are suddenly going to be a bunch more users that can potentially use IPv6. And these users are the type who are going to be especially sensitive to latency, jitter and packet loss, since this is a real-time game platform. For those of you with Help Desks who have to support users like this, the associated setting in the game's Options menu is apparently called "Enable IPv6 when available". It's apparently grayed out if you do not have IPv6 at all, unchecked by default if you are on 6to4 or Teredo, and checked by default if you are on native v6. The tooltip says: "Enables the use of IPv6, the technology behind the next-generation Internet. Requires IPv6 connectivity to the internet. Checking this box without IPv6 connectivity may prevent you from playing WoW." Anyone from Activision/Blizzard who would like to chime in with more details? :) -- Kevin

IPv6-only Systems
by Cameron Byrne 09 Jun '11

FreeBSD is initiating IPv6-only validation work http://www.prweb.com/releases/2011/6/prweb8529718.htm My own testing of the Windows 7 shows that, at it's core, it works well as IPv6-only for most "web & email" functions. Layering on applications like Skype, things start to fall apart. Cameron

Be aware of SLAAC adresses
by Jérôme Nicolle 08 Jun '11

08 Jun '11

Hi ! To all contributors to this wonderful IPv6 day, juste a short notice : please avoid SLAAC adresses on your public servers ! First, in case of an hardware crash, the recovery will be done under presure and most will forget about forcing the new server's mac adress to the old one, wich will delay the recovery Second, it's beeing a little too transparent as the MAC adress may reveal the server's manufacturer, approximate manufacturing tdate, or the network controler model. Some may use it as a clue to design a proper exploit... Just a nightly thought while monitoring seen IPv6 adresses ;) -- Jérôme Nicolle

Youtube?

I am having issues with Youtube getting stuck in i2.ytimg.com - the page comes up, a black box for the video but then hangs on i1 or i2.ytimg.com on in Firefox - not IE). IPv6 related? I have tried via 2 different ISPs and all show the same black box. -Hank

re: Cogent & HE
by Nick Olsen 08 Jun '11

Correct, The only way around this currently is to peer with both cogent and HE. If you have cogent, You can 6to4 w/BGP with HE. I would consider that just a patch for the problem. I would do it just for the reachablility.

Looks like we have different Global IPv6 tables? Or does Cogent just NOT peer IPv6 peer with anyone else! Dennis

There is some difference in prefix count between the two: AS6939 6074 AS174 4787 These are prefixes announced to transitcustomer of both HE and Cogent. -- Fredrik Holmqvist I2B (Internet 2 Business) 070-740 5033
