I've created the fastest open-source DNS bruteforcer using XF_ADP
An experimental high-performance DNS query bruteforce tool built with AF_XDP for extremely fast and accurate bulk DNS lookups. - c3l3si4n/pugdns
I've created the fastest open-source DNS bruteforcer using XF_ADP launched on March 20, 2025 with 15 votes, #1,370 of 7,215 launches that month and more than 75% of that year's launches. The site was still online in September 2026, 1 year on.
In plain words
This is an open-source DNS bruteforcer built with XF_ADP technology, designed for developers and security professionals who need to discover DNS records. The tool is optimized for speed and available on GitHub as a command-line utility. It targets users performing security testing, reconnaissance, and DNS enumeration tasks who require fast, reliable results from an open-source solution.

From the sources
pugDNS sends and receives DNS packets with AF_XDP and eBPF/XDP. The program is written in the Rust language. Use pugDNS only on the networks that you have permission to test. A bulk DNS scan sends a large quantity of traffic. This traffic can cause damage to a network. pugDNS makes the Ethernet, IPv4, UDP, and DNS packets in user space. It then puts the packets into the AF_XDP rings. Thus the packets do not go through the usual Linux UDP socket path. An eBPF/XDP program collects the replies. A query engine then examines each reply. pugDNS resolves millions of names in seconds. A test at 1 Gbit/s gave these results: # domains.txt www.example.com api.example.com # resolvers.txt 1.1.1.1…from github.com

DN$ – an innovative, ad-supported DNS resolver2024 · github.com · ▲294Tired 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…

Every privacy-focused DNS service requires an account: NextDNS, Cloudflare for Families, Apple's iCloud Private Relay (paid, iOS-only). The protocol that doesn’t require one - ODoH - had basically one well-known public relay operator (Frank Denis on Fastly Compute, default in dnscrypt-proxy). I built a second one and the client to talk to it.

Talanoa▲346Hi 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…
