About DNSX
Free, fast, and reliable network diagnostic tools built by developers, for developers.
Our Story
DNSX was born from a simple frustration: existing DNS and network diagnostic tools were either cluttered with ads, slow, or missing the features that developers and IT professionals actually need.
Created by a hobbyist working in IT and software development, DNSX started as a side project to solve problems that no one else had tackled quite right. We wanted a tool that was fast, clean, and actually useful — one that shows you not just the data, but helps you understand what it means.
Today, DNSX offers comprehensive DNS lookups with flow visualization, IP geolocation with ASN information, SSL certificate analysis, WHOIS data, and email authentication checking — all in one place, all completely free.
