I have IPv4 from my ISP, and a Hurricane Electric tunnel to provide IPv6, because my ISP is lame. (Hello, Verizon FIOS.) Netflix prefers IPv6. However, they have blacklisted the Hurricane Electric endpoints, because their paying customers with valid accounts might use those endpoints to view the content that they paid for while sitting in another country. The blacklist does not take effect until you try to actually get video content from Netflix, at which point an error is returned. The result of all this is that fast.com measures the speed of my IPv6 tunnel to Netflix CDN servers, which will not serve content. I have to turn off IPv6 routing on boxes in my house that want to watch Netflix, and then it falls back to IPv4... a completely different path than the one fast.com has just measured.
