Rick, feel free to stop reading and feel free to not respond. That's
your right, it's all up to you from here. If you read on and respond, I
don't want to hear anything more about wasting anyone's time. If you
want to respond with something snarky just keep it to yourself.


Domain name + requesting IP address, that's all I need to know to have
valuable data.


I'll be blunt as well. I think this argument is a strawman because you
lumped opennic in with other dns providers and dismissed them, and I
called out the differences. Did you not know that they also encourage
people to run their own nameservers? You did not go in depth in your
dismissal, I went in depth in my rebuttal and you haven't done anything
to rebut my arguments but make vague comments and be insulting.

I take the view that if everyone ran their own caching resolver or
otherwise stopped using the big dns providers, that those people would
do anything they can do get that data. That's not hard to understand or
imagine I'm sure.

Hahaha you can read or not. You can respond or not. I don't control
your time, as you mention below. So stop complaining about how you
spend your own time.

Uh okay. Here's the quote. If you weren't talking about a hypothetical
alternative dns provider here, then I'm not the only one here that's
confused.

"Ideally, one has a contractual relationship with a reputable good
provider who looks after customer interests in accordance to local
business practices and law, such as (to cite the USA local legal
concept) the implied covenant of good faith and fair
dealing. However,
that contract concept is (naturally) not a shield for privacy but
rather
a cudgel to wield in civil litigation, so the best thing to do is to
limit what your immediate uplink can learn about your network traffic.
Various crypto schemes help limit that data, but -- my point -- so
does
operating a local recursive nameserver, rather than outsourcing to
-anyone- on the other side of the uplink."

You lumped opennic in with cisco, google, and various others is what
you did. I didn't ignore it, I chose to defend opennic and point out
why they'r different, and I pointed out that they encourage people to
run their own servers. I made good and valid points. And you setup a
strawman in response and are now complaining about wasting time.

Again, you control what you do. Take responsibility for it.

You lumped them in with others who are entirely different, and I
pointed out how they're different and better, and you ignore everything
good I said about them.

Totally agree, trying to explain to you the difference between opennic
and other dns providers was a waste of time. And apparently, trying to
convince you that running a caching dns resolver isn't a long-term
privacy guarantee, is also a waste of time.
