CenturyLink, major telecom in 37 US states. DNS requests for all nonexistent domains go to a server that delivers a dumb "search" page to web requests. They're currently the sole fiber-to-the-home provider in my neighborhood, and Comcast is the only broadband alternative.

So one or two ISPs in one country out of 300+ worldwide. Hardly “most” ISPs as claimed in the post I replied to. Not even a fraction.

Here's an incomplete list with dozens.

What I don't understand is how these services are offered at apparently no cost. Sure, I expect Google is slurping all of my connections to help build an ad profile on me. But what about the other companies? They've got to keep the lights on somehow.

Google says they don't - from https://developers.google.com/speed/public-dns/privacy:

Honestly, Google DNS policy seems largely similar to Cloudflare, with the exception of 3rd party audit.

Cloudfare apparently doesn't do GeoIP mapping, so, till they implement that, it's not going to be useful for me.

Does no one bother to run their own DNS server? It's not hard---in fact, it's easier than running an authoritative DNS server, since you are only using it for local resolving. I ran the provided script, added my own local resolver, and after the first run, got incredibly fast results. test1 test2 test3 test4 test5 test6 test7 test8 test9 test10 Average cloudflare 35 ms 38 ms 39 ms 33 ms 34 ms 39 ms 28 ms 33 ms 28 ms…

Most people are not very interested in testing how fast their local machine can talk to itself; regardless of how fast your local cache is, it will have to talk outside pretty often (for expiring TTL if nothing else).

People are praising CloudFlare for not bothering to log requests. Yes, well ... you get the same results by using your own DNS resolver, and you don't have to be shocked when five years later a different governing team running CloudFlare decide to reverse their stance and log everything ...

But what do I know? Apparently I'm in the minority for running my own infrastructure (DNS, web, mail).
