In a perfect world you don't, but many ISP's block torrentsites by poisoning their own dns lookups to torrentengine domains and even some torrenttrackers. (They purposefully send you back a wrong IP when your pc asks where the website is, usually one that goes to a "this website is blocked" webpage instead).

If you use an open one you kinda circumvent this measure and you can get on any site again without any further hassle. There's Google's 8.8.8.8 and 8.8.4.4, cloudflare's 1.1.1.1, there's also 9.9.9.9, or if you are a techy you can even run a dns server yourself and then point to localhost.

Anyway, in my previous post I first said it ended on "dot io", but was wrong and then edited it to "dot to", but since edits don't always federate well I'm repeating now it is '.to', and not '.io'. 😜

Hey, I mentioned the self-hosting way of doing it, but it's not for everyone. Google and Cloudflare are just easy to remember, yet just (arguably bad) examples. But in the end any company can't be trusted anyway. Google once promised to keep your privacy and to never spy or give ads, so did Facebook at the start to get you away from "Evil data-seller MySpace". In the end you're just giving info to a new company that one day can start using it against you too, and if past is any indication, they either disappear or start doing it,... Correct me if I'm overseeing something now, but I can't think of anything that got popular and didn't abuse its power...

Anyway, though maybe a good ad-profile source, for the few that still have direct IP's (which is getting constantly smaller among consumers) these days with CGNAT and hotspots, it gets hard to identify someone over the limited info of a DNS request. In any case, going completely self-hosted is sadly not possible in a single sweep so you'll always have things that remain centralized throughout the switch, and even if you could, DNS will always be the biggest centralized entity. The root-dns servers all the way at the top (I have been taught in an IT catch-up education thing not so very long ago there's apparently just 5 keys, owned by 5 people) still would have some control cause the centralization of them is a necessity for having constant global consensus over a single internet. Until someone comes up with a decent genious ad-hoc federated dnsservice-alternative idea one day (and somehow would get all registrars with current running contracts on board) we're stuck with it, which is gonna be for still quite some time, I'm afraid... 😅

Anyway, that all being said, none of the above is meant as an excuse. I do also see the irony of suggesting a Google thing in an anti-company-dependence place, but in all honesty, I hadn't even connected those dots until now. 😅 I did not do it out of bad intent anyway, so also: my apologies. 😉
