Products that do what Add OpenDNS servers to resolve names with most recent successful entry does

If my experience is any indicator, the DNS issue seems to be getting worse as the hours go by, not better. However, I have found that adding OpenDNS servers (208.67.222.222, 208.67.222.222) to my list of DNS servers has completely eliminated the issue, at least for the time being. So, under my IPv4 configuration, in the "DNS Servers" field, I have "208.67.222.222, 208.67.222.222, 8.8.8.8" - the last one is the Google DNS server. I'm able to resolve Twitter, Github, etc.

   DN$ – an innovative, ad-supported DNS resolver▲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 libraries▲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.

   Open database tracking 77K public DNS servers every 10 minutes▲7

   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…

   I built a guided Build your own DNS Server challenge▲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…

    An API to provision custom hostnames with SSL▲90

    We launched an API for custom hostnames today. A simple HTTP post with a hostname gets a temp hostname with CNAME/a record instructions, as soon as DNS is setup we issue SSL and start accepting traffic for that hostname. It's the quickest way we know of to provision custom hostnames: https://fly.io/mix/custom-hostnames/ When we started building Fly, we figured it was too late to "make SSL easy and the customers will come". Lets Encrypt changed the world, and we knew many companies rolling their own SSL support with nginx, Traefik, etc, etc. It seemed like a…

    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!

    OctoDNS, Tools for managing DNS across multiple providers▲31

    After the major outages from AWS and Cloudflare, I began wondering how to make my own services more resilient. Using nameservers from different providers is doable but a bit tricky to manage. OctoDNS helps automate keeping the zones synced so AWS, Cloudflare, etc. are all serving the same information. In an age of centralized infrastructure, we can exploit the capabilities from the origins of the decentralized internet.

    Shiddns a DNS learning experience in Python▲7

    Hi HN, as a learning experience, I created a small DNS resolver with blocking capabilities and resolution of local host names. There are already tons of good ad-blocking DNS implementations out there. And they do this much better than my implementation. Great examples are Blocky or pihole. So when I set out to "play around", I looked at these projects and tried to modify them. Fortunately for them, but unfortunately for beginners, these are already quite far developed and complex projects. So impatient me set out to "quickly write something in Python". Almost two weekends later, I put in so…

    Backname.io – every IP address gets its own domain▲46

    I was setting up tests involving DNS resolution recently, where something like 127.0.0.1.service.foo would have been tremendously useful. Back in the day, I'd have used xip.io - but sadly that service died. Well, every excuse is a good one when it comes to writing a DNS server! Backname.io joins nip.io and sslip.io in the wildcard DNS game.
