The idiocy around IPv6 is astounding.
IPv6's reputation? Really? Just because you think you understand IPv4 does not qualify you to judge what is relevant in v6 even if 128 bit addresses are hard for you. The issues surrounding IPv6 deployment have nothing to do with "Oh Joe won't understand these long IPs in his home device assignment plan" but most ISP's delaying rollouts.
NAT provides security? Get over it, the CPU overhead alone isn't worth it, something even the likes of you will fathom when you start to hit 100 Mbit or faster connections on ye old home router. Stop using IPv4 hacks. Lookup IPv6 privacy extensions, something Windows enables by default.
The "P" in VPN stands for Private, implying encryption. While it's possible to setup a VPN to use null encryption, it's not the standard case. A tunnel, 6in4 or other, is not a VPN or a proxy while it might seem like that to what appears to be the average Slashdot user today.
Downgrade Netflix to IPv4 in your firewall as suggested by others to work around this, if you're v6 only, yell at Netflix.
An even worse hack is to prefer IPv4 over v6, this is so bad that even MS recommends against disabling IPv6 or changing preferred order.
