Netflix, IPv6 and "You seem to be using an unblocker or proxy."

Trying to watch a movie via Netflix, I get:

Whoops, something went wrong...
Streaming Error
You seem to be using an unblocker or proxy. Please turn off any of these services and try again. For more help, visit netflix.com/proxy. 

Error Code: M7111-1331-5059


The cause seems to be that I use an IPv6 tunnel (from Hurrican Electric). See http://seclists.org/nanog/2016/Jun/26 .
Great ... :-(

I don't understand why Netflix doesn't use IPv4 to detect the real origin of the customer, and then offers the 'correct'/meant offering via IPv6.


Anyway. Workarounds:

IPv6 traffic is the majority of my Internet traffic


Interesting: IPv6 traffic is the majority of my Internet traffic at home: 54%. And IPv4 is the minority.

Calculation (thanks to the MRTG monitoring of my router):

  • IPv6 traffic has an average of 366.0 kb/s
  • Total IPv4+IPv6 traffic has an average of 676.4 kb/s

So divide those numbers IPv6 by total traffic: 366/676 = 54% IPv6 traffic.

The explanation is quite easy: the well-known high-traffic sites (youtube, google, facebook) are IPv6-enabled.

PS: If "an average 676.4 kb/s" sounds low: that's almost 7GB per day. Rule of thumb: 100 kbps average is 1GB per day.

MRTG overview of my traffic: Green is total traffic, Blue is IPv6. Note there are only two IPv4-spikes.

Nice tool to find info about IPv6 addresses

The site http://ipinfo.io/ offers info about IPv6 addressess:

$ curl ipinfo.io/2001:888:0:18::80
{
  "ip": "2001:888:0:18::80",
  "hostname": "www.xs4all.nl",
  "city": null,
  "country": "NL",
  "loc": "52.5000,5.7500",
  "org": "AS3265 Xs4all Internet BV"
}

If you only want the country:

$ curl ipinfo.io/2001:888:0:18::80/country
NL

To find your own country ;-)

$ python -c "import urllib2; print urllib2.urlopen(urllib2.Request('http://ipinfo.io/country', headers={'User-Agent' : 'curl'})).read() "

NL


Let's try HTTPS:

$ curl https://ipinfo.io/2001:888:0:18::80
SSL access is restricted to paid plans. See http://ipinfo.io/pricing for more details

... ah ... pity.

Ziggo at 8% IPv6 ... but has turned it off again?

That looks impressive: according to worldipv6launch Ziggo is at 8% IPv6 traffic (from 1% one month earlier):





But does this tweet between @iljitsch and @ziggowebcare mean Ziggo has turnef off IPv6?
