uocou-chekip

A minimalist IP checker built with Cloudflare Pages + Pages Functions. Clean, fast, and ready to deploy.

Demo: https://ip.uocou.com

• CN 中文说明

• Pure static front-end + serverless APIs: index.html / public/style.css / public/app.js
• Centered card, compact two‑column layout
• Clean visual style with subtle shadows & spacing
• Smooth focus & hover states for inputs and buttons

• Clear page title and landmarks
• Keyboard-friendly focus outlines
• Accessible button and input attributes

• No framework, no build step
• Edge‑side caching for third‑party lookups
• Minimal JavaScript, no external dependencies

• Cloudflare Pages + Pages Functions (no server to maintain)
• Uses Cloudflare Edge info for ASN/Org
• ISP via ipwho.is (with fallback in lookup)

IP | Country
Region/State | City
Postal Code | ASN
ASN Organization | ISP

ASN/ASN Organization come from Cloudflare edge (BGP), while ISP comes from ipwho.is (access/retail brand).
They can differ — this is expected (different data sources/perspectives).

git clone https://github.com/uocou/uocou-chekip.git
cd uocou-chekip

Best (with Cloudflare Functions):

npm i -g wrangler
wrangler pages dev .
# usually served at http://127.0.0.1:8788

Simplest (UI only; APIs won't work locally):

# with Python
python -m http.server 8000
# or open index.html directly in your browser

1. Cloudflare Dashboard → Pages → Create a project → Connect to Git → choose this repo
2. Build settings:
   • Build command: (leave empty)
   • Output directory: /
3. After deploy:
   • https://<your-project>.pages.dev/ (Home)
   • https://<your-project>.pages.dev/api/me (Edge JSON)
   • https://<your-project>.pages.dev/api/isp (ISP JSON)
   • https://<your-project>.pages.dev/api/lookup?ip=8.8.8.8 (Lookup API)

• /api/me: Cloudflare edge metadata only (no third‑party).
• /api/isp & /api/lookup: use ipwho.is, cached ~120s; lookup falls back to ipapi.co.
• To avoid third‑party entirely, remove the ISP card and related API calls.

• Cloudflare Pages / Pages Functions
• HTML + CSS + Vanilla JS
• No frameworks, no bundlers
