They do but that is irrelevant. Blocking just that one /64 prefix works 
because that is where their tunnel detector apparently lives.

I think we are at the point where we can say it would be nice if Netflix 
could just redirect users from IPv6 to IPv4 when a tunnel is suspected. 
They do deserve flames for being bad guys here when they have such an 
easy out.

But you can also just fix the issue yourself with a simple firewall rule.
