Den EU-finanzierten DNS-Dienst #DNS4EU kann ich nicht empfehlen, weil Zugriffe protokolliert werden - bei "schädlichen Inhalten" sogar mitsamt IP-Adresse. https://www.techradar.com/vpn/vpn-privacy-security/the-eu-challenges-google-and-cloudflare-with-its-very-own-dns-resolver-that-can-filter-dangerous-traffic
Es gibt gute nichtstaatliche Alternativen: https://www.privacy-handbuch.de/handbuch_93d.htm
Update: Es scheint, die IP-Speicherung erfolgt im o.g. Fall für 24 Stunden, damit die Warnung vor den Inhalten nicht immer wieder angezeigt wird.
I can't recommend the EU-funded DNS service #DNS4EU because access is logged. When you override warnings to access "harmful websites" they even log your IP address. https://www.techradar.com/vpn/vpn-privacy-security/the-eu-challenges-google-and-cloudflare-with-its-very-own-dns-resolver-that-can-filter-dangerous-traffic
There are government-free services that do not log: https://www.privacyguides.org/en/dns
Update: I understand now the IP address is kept for 24 hours to prevent the confirmation prompt from showing again.
@echo_pbreyer That doesn't seem to say that they log the IP?
It sounds like they keep your IP* in memory so you don't get reprompted about a site that you've chosen to bypass warnings on.
IMO, that's a *good* thing because it means average consumers won't simply switch away from the service if it accidentally overblocks
*In fact, not your IP, they've gone to quite extreme lengths to anonymise - they're not just masking octets, it all gets HMAC'd with a rotating key: https://142290803.fs1.hubspotusercontent-eu1.net/hubfs/142290803/DNS4EU%20Public%20DNS%20Resolver%20policy%202025.docx.pdf
@ben Ah, I understand now. Ok, that makes sense. But they could do better than storing plaintext IP addresses, no?
What they're doing can only be achieved by storing some of kind of unique (and semi-persistent) identifier.
The only information available to them to identify the user is an IP, so whatever they do will always have to be derived from that - at a certain point, you're adding computational cost for no routine privacy benefit (where there is benefit though, is if that information somehow leaks).
I think they could do more, but they're also already well above most other providers
