Products that do what Ldns.com – fast DNS lookups from the URL bar does
I built LDNS because I'm constantly curious about domain names - who owns them, which nameservers they use, how they're configured, and what their DNS records reveal. I wanted a fast, easy way to investigate domains right from my browser without juggling multiple tools. LDNS runs entirely client-side using Cloudflare's DNS over HTTPS. Just type a domain and instantly see: All DNS records with clickable filtering RDAP/WHOIS data with registrar info and expiration dates Email security configuration (SPF, DMARC, MTA-STS, BIMI) Export options (JSON, CSV, BIND zones, PDF reports) Try it at…

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 built DomainExplorer.io, a search and analytics tool that lets you explore newly registered and expired domains across all TLDs — updated daily. The idea came from my frustration how hard it is to search for registered/expired domains. I wanted a simple and easy-to-use tool with web UI where you could submit queries like: - Find all domains in .com and .net zones that end with "chatgpt". - Find all expired domains that have "copilot" substring in name (excluding .ai and .io zones) and their name is shorter than 12 symbols - Find all domains with "amazon" in name and that were…

Domainy is a tool to get alerted on when the domain names you like and want are about to expire and also become available. https://www.domainy.io A few use cases - I'm monitoring all the other TLD domain names for which I would like to eventually acquire to protect brand names for the domain names that I already have (e.g. I have google.com and I want to make sure that I have google.abcde, google.edfg etc etc) - I also want to know when some of the domains that I would like will expire and possibly become available, so I can quickly buy them if I can. Just because a domain is…

I get at least one phishing text message every week, and discovered that reporting malicious domains was a major hassle. You have to first manually do a whois lookup, and since not every registrar includes an abuse contact email in their whois record, you often have to then go to the registrar's website and try to find their abuse reporting section before you can report the domain. I figured something had to exist already for reporting domains directly to their registrars, but I couldn't find anything, so I spun up DomainReporter mostly as a tool to use myself, but also to make the process…

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…
