Our Story

From an idea to an ecosystem

It all began with a simple question: why should checking DNS be so complicated? We set out to build tools that were fast, accurate and accessible to everyone — not just experts.

As users joined and feedback arrived, the platform grew. One tool became dozens, and every new feature answered a real, reported need.

Our Mission

We make web-infrastructure tools simple, fast and dependable — with deep respect for privacy, and continuous innovation driven by our community's feedback.

Our Journey

The WhoDNS timeline

1401

The idea is born

The initial idea for WhoDNS took shape — a simple thought to simplify DNS analysis and make network tools accessible to everyone.

1402

Development begins

In late 1402 development officially began. The first versions focused almost entirely on DNS inspection and WHOIS tools — fast, accurate and accessible.

1405

A new chapter with IranServer

A major milestone. With the support of IranServer, the platform was redesigned from the ground up: better performance, a cleaner interface, new services and more powerful, scalable infrastructure.

Today

A growing ecosystem

Today WhoDNS is no longer just a DNS checker; it has become a growing ecosystem of professional web and infrastructure tools that save you time. And the journey is only just beginning.

Great tools don't just solve problems. They make people enjoy solving them.

We are still writing this story. Every feature we build, every bug we fix and every improvement we make is inspired by the people who use WhoDNS every day.

Thank you for being part of our journey.
