ipv6 Google services
« on: November 10, 2014, 06:27:29 PM »

Hi,

I have a problem with gmail, youtube etc over ipv6 tunnel, the problem is google open to slow, youtube i'm getting ridiculous slow speed, in youtube i'm getting in whatever video speed 50 kbits/s to 200 kbits/s with a connection 10 mbits/s and if i disable IPv6 i'm getting normal speed in Youtube and other google services not slow me.

What is the cause of the issue? this happend in the begin (around 2 years) and yesterday i notice this is the cause of the issue. I've lived all this time deceived thinking it was my ISP

It still may be your ISP.  The routes via IPv4 and IPv6 to your destination are probably radically different.

Here's a public address lookup of youtube.com:

Code: [Select]
2607:f8b0:4000:806::1005
173.194.115.129
173.194.115.132
173.194.115.128
173.194.115.135
173.194.115.130
173.194.115.133
173.194.115.136
173.194.115.134
173.194.115.137
173.194.115.131
173.194.115.142

And for www.youtube.com:

Code: [Select]
2607:f8b0:4000:804::1005
74.125.227.231
74.125.227.224
74.125.227.227
74.125.227.229
74.125.227.228
74.125.227.226
74.125.227.230
74.125.227.233
74.125.227.232
74.125.227.225
74.125.227.238

So...  One IPv6 address for each domain and...a whole lot of IPv4 addresses for each domain.  Why is this a problem?  Well, the following people are using IPv6 to access these services:

1. Everyone with Android 4 on T-Mobile.
2. Everyone with an LTE phone on Verizon.
3. A massive number of people on Comcast.

Seems to be a bit much for that one IPv6 host...
