Google has started to initiate the enabling of their Youtube site over IPv6.
It is currently available to participants in their Google over IPv6
program, http://www.google.com/intl/en/ipv6/ .


The www.youtube.com user interface so far does *not* have any AAAA
published, but the *much* more important (traffic wise) image and video
servers do.


:~$ host s.ytimg.com
s.ytimg.com is an alias for static.cache.l.google.com.
static.cache.l.google.com has address 74.125.13.213
static.cache.l.google.com has IPv6 address 2001:4860:4001:402::15

 

:~$ host v1.lscache1.c.youtube.com
v1.lscache1.c.youtube.com is an alias for v1.lscache1.l.google.com.
v1.lscache1.l.google.com has address 74.125.97.80
v1.lscache1.l.google.com has IPv6 address 2001:4860:4001:402::10
