  • Nice project and poc maybe, but I'm not seeing the practical application of this in a real world env, surely the latency is a deal breaker ?

  • There's no point in using PlatformIO for ESP32 MCUs. The native ESP-IDF extension works much better.

    I would only recommend using it instead of the standard Arduino Processing IDE.

    Please just write the first sentence of your README yourself

  • Whitelist/allowlist is easier, e.g., it's smaller

    Depends on the user but not everyone is visiting new websites everyday

    Even for those that are, the number of domain-IP mappings needed will be relatively small

    Definitely under 140,000

    Most DNS data I use is "static", it rarely changes. As such most times I don't have to make DNS queries. I store the domain-IP mappings in proxy memory; this is faster than DNS

    No "blocklist" needed

  • I think it could fit even more domains using a Bloom Filter or similar probabilistic data structure. With a chance of false-positives of course. But that's a trade-off the project already makes.

  • I'm a bit of a paranoid freak that likes lists, so I've got a PiHole that has a total list of 14-16M blocked domains.

    Great idea, and good for casual blocking, but I'm almost moving to an "allow list" mindset. This solution would probably work better for that, I wonder if the good parts of the internet would fit into an 140k list.

  • If you're ever thinking about getting an ESP32-C3, do yourself a favor and get the variant that you can connect an external antenna to. The normal C3 has a built-in antenna that is extremely weak, making it useless for most things I was planning using it for.

  • Weird how the readme talks about hash collisions, but not in the way I would expect. Two blocked domains with the same hash isn't a problem, they both need to be blocked.

    Where hash collisions matter is false positives, e.g. if hash(google.com) = hash(adserver.com). There does appear to be a web dashboard and /unblock api so should be straightforward to resolve.
