4B+ DNS Records Dataset
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!
4B+ DNS Records Dataset launched on October 15, 2024 with 90 votes, #574 of 5,185 launches that month and more than 90% of that year's launches. The site was still online in September 2026, 2 years on.
In plain words
The 4B+ DNS Records Dataset is a collection of approximately four billion DNS records covering all major record types including A, AAAA, MX, CNAME, and others. Researchers and competitive analysts use this dataset to study internet infrastructure and analyze DNS landscapes. Each record is formatted as a simple CSV with domain, record type, and value, making it accessible for large-scale internet research and analysis.

Talanoa▲341Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
