About
ipchu
Fast, ad-free IP lookup — built for everyone
Why we built this
Every time we searched "what is my IP", the results were the same: pages plastered with banner ads, cookie consent walls stacked three layers deep, and a simple number buried under sponsored results. The tools that weren't ad-heavy were slow — loading megabytes of JavaScript just to fetch an IP address that the server already knew.
ipchu exists to fix that. Your IP address is rendered server-side at Cloudflare's edge and is on screen before a single line of client JavaScript runs. No fetch delay, no spinner, no ads.
What we believe
- Speed is a feature. Every millisecond of loading time is a tax on the user. We optimise relentlessly.
- Your data is yours. We process your IP to answer your question and discard it immediately — nothing is stored.
- Useful tools should be free. ipchu is free to use, with no account required, no paywalled features, and no tricks.
- Clutter is a choice. We chose against it.
The name
ipchu is a play on IP (the internet protocol address we look up) and 立秋 (lìqiū, pronounced roughly "lee-choh") — the 13th of the 24 traditional East Asian solar terms, marking the start of autumn. It falls each year around August 7th.
We liked the coincidence: a tool that tells you where you are on the internet, named after a calendar marker that tells you where you are in the year. If you visit on 立秋 day, you might notice something on the page.
What's under the hood
- Hosting: Cloudflare Pages — deployed globally at the edge, no origin server latency.
- IP data: Derived from Cloudflare's request headers (
CF-IPCountry,CF-IPCity, etc.) — no third-party geolocation API call on the critical path. - Framework: Astro with server-side rendering — ships near-zero JavaScript to the browser.
- DNS leak test: Backed by a real authoritative DNS server — not a simulated check.
- Analytics: Google Analytics 4 with anonymised IPs — used only to understand aggregate usage patterns and improve the product.
The free API
ipchu.com/api/ip returns your IP, location, ISP, ASN, and timezone as JSON. No API key, no registration, no rate limit for reasonable use. If you are building something that needs IP data, use it.
