Products that do what Open database tracking 77K public DNS servers every 10 minutes does

Hey HN! We built DNS Directory (https://dnsdirectory.com), a free, searchable database of public DNS servers with live monitoring every 10 minutes. We needed to find an up-to-date list of DNS servers used by carriers around the world for a proxy fingerprinting / web-scraping project but we were shocked to find that it didn’t exist so we built it ourselves in an internal Hackathon We’re adding more features but so far we: Test 77K+ servers every ~10 minutes Allow filtering by uptime, location, security features (ad blocking, malware protection, DNSSEC) Show info on IPv6…

    Tired of companies snooping through your DNS traffic? Don't you wish you could get advertisements with your DNS records? Today we're introducing the innovative, privacy-focused, ad-supported DNS resolver - DN$! Traditional DNS resolvers provided by your internet service provider, cloudflare, or google could be tracking your internet activity and selling it to third-party data vendors. We at DN$ want to fix that and cut out these nefarious actors (until we've amassed a critical number of users to exploit). In order to support such a radically new business model, our service needs to serve…

    Hi HN, I've been working on building a pipeline to create a DNS records database lately. The goal is to enable research as well as competitive landscape analysis on the internet. The dataset for now spans around 4 billion records and covers all the common DNS record types: A AAAA ANAME CAA CNAME HINFO HTTPS MX NAPTR NS PTR SOA SRV SSHFP SVCB TLSA TXT Each line in the CSV file represents a single DNS record in the following format: www.example.com,A,93.184.215.14 Let me know if you have any questions or feedback!

    Hey everyone. It's Sherub here, author of the Build your own DNS Server challenge on CodeCrafters. Currently it’s available in Rust, Go, and Python and is free while in beta. https://codecrafters.io/dns-server I've kept the challenge accessible but still challenging for an intermediate developer. This challenge, like others from CodeCrafters, is self-paced. You can use any tools you prefer (terminal, editor, etc.) to build the project. At the end of the challenge, you will have created a DNS forwarding server. The server can create and read DNS packets and respond to DNS…

    Most site blockers work by blacklisting distractions. That never worked for me, the internet is too big, and there’s always something new to waste time on. I wanted the opposite: allowlist‑only browsing. Block everything by default, and explicitly allow only what I need. So I built Sinkzone: a local DNS forwarder with two modes: Monitor mode: lets all traffic through, but logs every domain so you can decide what to allow. Focus mode: only allowlisted domains resolve; everything else is blocked (NXDOMAIN). It’s open source, written in Go, and runs locally on macOS, Linux, and Windows. Works a…

    We’ve just launched NUM [1] in the UK, it’s an alternative to the semantic web [2] but based in DNS. We’ve published 23 million data points about 4.8m UK businesses. We had some really interesting HN feedback when we previously posted about one of our example apps [3] so keen to hear what the community has to say this time round. 1. https://www.num.uk 2. https://num.uk/blog/we-crawled-5m-uk-websites-and-published-23m-data-points-to-dns 3. https://news.ycombinator.com/item?id=27598164
