Open-Source Unbound DNS Resolver Docker Image

In plain words

This is a Docker image containing an open-source Unbound DNS resolver, designed for system administrators who want to run their own DNS infrastructure independently from their internet service provider. It aims to provide improved privacy and avoid DNS-based censorship. The image is built transparently using online workflows, allowing users to verify its contents and ensure nothing has been tampered with during the build process.

Hey Hacker News! I am madnuttah, I am a Windows/Linux Sysadmin and some folks may remember this username for "niche" mods I've made for Fallout and Skyrim and some C# UWP Windows Store Apps which I've retired because of Microsoft's unclear strategy abandoning things from one day to another.

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

  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…

  I built a DNS resolver from scratch in Rust – no DNS librariesApr 2026 · github.com · ▲115

  I built a DNS resolver that lets me use https://frontend.numa instead of localhost:5173 — auto-generated TLS certs, WebSocket passthrough, path routing. No mkcert, no nginx, no /etc/hosts.

  I've built a nice home server OSApr 2026 · lightwhale.asklandd.dk · ▲194

  ohai! I've released Lightwhale 3, which is possibly the easiest way to self-host Docker containers. It's a free, immutable Linux system purpose-built to live-boot straight into a working Docker Engine, thereby shortcutting the need for installation, configuration, and maintenance. Its simple design makes it easy to learn, and its low memory footprint should make it especially attractive during these times of RAMageddon. If this has piqued your interest, do check it out, along with its easy-to-follow Getting Started guide. In any event, have a nice day! =)

  I built a guided Build your own DNS Server challenge2023 · app.codecrafters.io · ▲57

  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…

  Talanoa▲346

  Hi 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…
