Hey HN, I saw a thread a while ago (linked in README) discussing how Wikipedia does a good job keeping track of the domains of websites like Sci-Hub or The Pirate Bay. Someone mentioned checking Wikipedia to find links to these sites, so I thought this would be a fun thing to automate! To try it out, install an extension or modify your hosts file, then type in the name of a website with the TLD `.idk`. For example: scihub.idk -> sci-hub.tw Cheers!

Free & Private domain research - right in your browser

In my exploration of OpenAI, I just created a domain-name search that takes business description as an input, and generates interesting domain names for it. It then uses DNSimple API to check if .com is available. In my view it is a much easier way to find a suitable domain, as the AI thinks of a much large pool of possible names than my own brain. SmartyNames found its own name, using the tool itself. Hope you enjoy it! https://smartynames.com/

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…

hey guys, wanted to show one of my side projects i just made public. the idea is basically another osint tool for pentesters and bug bounty hunters. it watches certificate transparency logs and checks newly-seen domains for exposed stuff like .env files, open .git dirs, config files, db dumps and so on, and puts whatever it finds into a searchable db. you just search a domain (or part of one) and see what's exposed. it's read-only and free. one thing i've been thinking about adding is a way to register for certain keywords and get notified when something new shows up for that search. would…

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…

Hi HN, This is a project [1] I've been working on for a little while and I'm interested in your feedback and point of view. Many of us would have verified a domain name by pasting a string into a DNS TXT record. Some providers ask us to store this DNS TXT record at a domain using a DNS label like "_provider" e.g. _provider.yourdomain.com, and some providers ask that you do it at the zone apex (God help us [2]). The Domain Verification protocol stores a DNS TXT record at a DNS name derived from a hashed "verifiable identifier" (think email, telephone, DID), enabling anyone that can prove…

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…
