YouTube's videos now available over IPv6
« on: January 29, 2010, 02:08:40 PM »

So while it hasn't been officially announced by Google/YouTube, yesterday around 1PM Pacific they pushed out AAAA records for their caching/streaming servers. If you are using Google white-listed recursors, and have IPv6 connectivity, you'll be watching videos served over IPv6. This is probably one of the (if not THE) largest pushes of content onto IPv6.

ipv6-ops mailing list thread starts here: http://lists.cluenet.de/pipermail/ipv6-ops/2010-January/002893.html

Code: [Select]
~$ host v10.lscache8.c.youtube.com
v10.lscache8.c.youtube.com is an alias for v10.lscache8.l.google.com.
v10.lscache8.l.google.com has address 74.125.103.84
v10.lscache8.l.google.com has IPv6 address 2001:4860:4001:402::14

Heh yeh I noticed when I was watching one of my subscription vids yesterday (I think it was yesterday) and gkrellm started showing a lot of traffic over the HE tunnel interface and realized the content was coming over IPv6 now.  Then a bit later I read that post in ipv6-ops.  Pretty big deal, and just a few days ago Comcast announced an IPv6 trial for users.

Way to go, Google!

It was announced and demonstrated (with tcpdump running) at Cisco Networkers 2010-01-28 in Barcelona, Spain, where they showed a video of the late "Itojun" (Dr. Junichiro Hagino).

From the program:

Abstract:

As we approach from the time where the IPv4 address pool will be fully exhausted, migration to IPv6 becomes an urgent item in all network managers' agenda.  A number of Internet community leaders have already started this migration process. They will describe how they are working through the IPv6 transition, exposing their own deployment success and challenges.

Might be a dumb question, but when will www.youtube.com respond to AAAA lookups?

You meant to do this:

Code: [Select]
host -6 www.youtube.com
 :)

Code: [Select]
[carl@mars ~]$ host youtube.com

Nah, that doesn't work either.

Code: [Select]
[carl@mars ~]$ host -6 youtube.com
youtube.com has address 74.125.127.100
youtube.com has address 74.125.45.100
youtube.com has address 74.125.67.100
youtube.com mail is handled by 10 sjl-mbox1.sjl.youtube.com.

Even so, the "dig aaaa" would return the answer I was looking for.

To see if a domain has a AAAA record you need use:
Code: [Select]
host -t aaaa www.youtube.comOtherwise it will just print the A record.

Not on any OS's I have looked at. It'll show A, AAAA and MX records by default.

Not quite true.  If you're using a google IPv6 whitlisted DNS server (such as the one HE offers), youtube.com does indeed have AAAA records:

dig www.youtube.com aaaa

We have a small confusion in this topic:

www.youtube.com has AAAA records and is yt main domain.
youtube.com is a set of redirectors pointing to the above host name (and it is without AAAA records).
