Re: Netflix VPN detection - actual engineer needed

It should be pointed out that -- the SPECIFIC accusation from Netflix -- is
that people on TunnelBroker are on a VPN or proxy unblocker.

The data does not bear that out.  Hash tag just saying.

The general lie that is IP Geolocation. HE only has what I tell them (100%
unverified), and what MaxMind (et.al.) tell them (~95% unverified.) They
know my IPv4 endpoint address, but that doesn't give them a concrete street
address -- they're guessing in exactly the same way everyone else does. And
more to the point, HE doesn't share that information with anyone. (whois is
populated with your account information. they don't ask where your tunnels
are going.)

Are they legally required to go to this level?


Possibly, but Netflix isn't going to push this. Win or Lose, they still
lose distribution rights.

Netflix (and their licensees) know people are using HE tunnels to get
around region restrictions. Their hands are tied; they have to show
they're doing something to limit this.


No, they do not know.  The purpose of HE tunnels is to get IPv6 service.
The fact that the endpoints are in different countries some of the time
is incidental to that.


YES. THEY. DO. There have been entire COMPANIES doing this. (which is
likely what sparked this level of response.) Neither HE nor Netflix are
naming names, but a short walk through the more colorful parts of the
internet should be enlightening.

Garbage.  You have to establish the tunnel which requires registering
a account.  It also requires a machine at the other end.  Virtual
or physical they don't move around the world in a DDNS update. The
addresses associated with a tunnel don't change for the life of
that tunnel.


True. 'tho, you can list any nonsense address you want. They do nothing to
validate it. (Use my favorite BS address: Independence MT -- pop: zero.
It's a dirt road across a mountain in the middle of absolutely nowhere.
Google it!)

The tunnel endpoint (your IPv4 address) is known only to HE, and not
exposed to ANYONE. That's not going to EVER change. Once your tunnel has
been setup, that address ("Client IPv4 Address") is not set in stone.
People have dynamic addresses, and HE recognizes this, so there are
numerous methods to change the tunnel endpoint address. (tunnel
configuration page, update through an http(s) request, etc.) THUS, a tunnel
can move; it can be terminated anywhere, at anytime. Not only can one
update the endpoint to a different address on the same box, but to a
completely different box entirely.

Furthermore, one account can have several tunnels through different
servers that present addresses from different regions. Where I appear to be
in the world, thus, depends on which tunnel I have enabled. (and in which
countries HE has prefixes, which currently appears to be 4)
