Show HN: A Simple, Fast, and Ad-Free Whois Lookup Tool

I built a lightweight WHOIS lookup tool that lets you quickly check domain and IP registration details directly from your browser:

It’s designed to be fast, readable, and distraction-free. No ads, no sign-up, no tracking scripts, just the information you need.

What it does : - WHOIS lookup for domains and IP addresses - Clear, structured output (registrar, dates, nameservers, ASN info when available) - Works instantly in the browser - No installation or account required

Why I built it : Most WHOIS tools today are overloaded with ads, captchas, or confusing layouts. I wanted something simple and reliable that works immediately when you need quick registration details or network ownership information.

This tool is part of a growing collection of free, browser-based network utilities, including IP lookup, port checker, DNS leak test, traceroute, SSL checker, and more:

Feedback welcome

I’d love feedback on the UI, missing fields, or ideas to improve accuracy or readability.

Thanks for checking it out!
