World IPv6 Day

Today is World IPv6 Day where a lot of major websites like Google or Facebook finally support IPv6 access for everyone. Unfortunately they plan to turn IPv6 access off tomorrow. 🙁

Well, this blog supports IPv6 since its creation. And I don’t have any plans to turn IPv6 access off. Oh, before I forget. Some people hid easter eggs in their IPv6 address:

> host -t aaaa www.facebook.com.
www.facebook.com has IPv6 address 2620::1c18:0:face:b00c:0:1

> host -t aaaa www.cisco.com.
www.cisco.com has IPv6 address 2001:420:80:1:c:15c0:d06:f00d

YouTube via IPv6

Google recently enabled IPv6 support for their popular video portal YouTube. This resulted in a significant increase of IPv6 traffic on the Internet. The amount of IPv6 traffic running through the DE-CIX e.g. grew roughly by a factor of four.

This is a big step in the right direction in my opinion. Finally a lot of popular content is made available to end users via IPv6. Thanks a lot Google!

I only wish they would admit more Internet Service Providers to the Google over IPv6 project. My ISP AAISP still cannot get access although they are among the few which offer native IPv6 connectivity to their customers. 🙁

Give me a ping, Vasili. One ping only, please.

A few month ago I discovered that Cisco broke IPv6 support in the IOS (Cisco’s operating system) that is running on my Cisco 877W router. This was quite annoying as IPv6 support was the only reason that I bought such an expensive router in the first place.

As my support contract doesn’t allow me to submit bug reports I had to open a service request. It took Cisco’s support organisation four weeks to reproduce the problem and another two month to submit a bug report. I wasn’t too impressed by these delays especially as I didn’t get any status updates for extended periods of time. When the bug had finally been reported to their engineering department I got an experimental firmware build with working IPv6 support within two weeks.

Considering that Cisco is a huge company I should probably be happy that they fixed the problem within three month. But I guess I’m still annoyed that they didn’t find such a fundamental problem before they released the software. A ping, one ping only, would have been enough.
