Show HN: Ldns.com – fast DNS lookups from the URL bar https://ift.tt/t7WpnjP

Show HN: Ldns.com – fast DNS lookups from the URL bar 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 ldns.com - just append any domain like ldns.com/example.com to start investigating. Built with SvelteKit and deployed on Cloudflare Pages for that instant-load experience we all love. Comments, feedback, and feature requests welcome! https://ldns.com/ August 15, 2025 at 11:46PM
