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 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.

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…

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. Why am I writing this? I wanted to be independent from the DNS servers of my provider, because they have often shined brightly with problems in the past instead of functioning properly, wanted to have a little bit more privacy and freedom back by fighting censorship via DNS, so I built my own Unbound…

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.

My goal was to create a DNS server as simple as the LDAP server I've been contributing to (glauth) and here it is: https://github.com/fusion/kittendns A few things to know about it: - It is easy to configure using a Toml file - I am using it to bail my coredns/etcd instances when under attack - (yes, it also works as a service location server) - It comes with a simple, plain English, rule engine that doesn't do much at this point - It can be used with LetsEncrypt. I use it to retrieve certificates for my home servers. - RFC: all the nice ones :) Anyway, feedback is…

To power the firewalling for our agents so that they couldn't contact arbitrary services, I build netfence. It's like Envoy but for eBPF filters. It allows you to define different DNS-based rules that are resolved in a local daemon to IPs, then pushed to the eBPF filter to allow traffic. By doing it this way, we can still allow DNS-defined rules, but prevent contacting random IPs. There's also no network performance penalty, since it's just DNS lookups and eBPF filters referencing memory. It also means you don't have to tamper with the base image, which the agent could potentially manipulate…

I built a CLI to benchmark DNS resolvers after discovering DNS was adding 300ms to my API requests. v0.3.0 just released with new features: compare: Test single domain across all resolvers top: Rank resolvers by latency/reliability/balanced monitor: Continuous tracking with threshold alerts 1,400+ downloads in first week. Quick start: pip install dns-benchmark-tool dns-benchmark compare --domain google.com CLI stays free forever. Hosted version (multi-region, historical tracking, alerts) coming Q1 2026.
