IPv4 & IPv6 Address Checker¶

A lightweight utility hosted on Cloudflare Pages that returns the user's public IP address as plain text. Perfect for CLI usage with curl or quick browser checks.

Usage¶

CLI¶

Get your default protocol IP (usually IPv4):
```
curl https://checkip.ipcow.com/
```
Example output: 1.0.0.1
Force IPv4:
```
curl -4 https://checkip.ipcow.com/
```
Example output: 1.0.0.1
Force IPv6:
```
curl -6 https://checkip.ipcow.com/
```
Example output: 2606:4700:4700::1001

Browser¶

Visit https://checkip.ipcow.com/
Displays your connecting IP (IPv4 or IPv6, depending on your browser’s protocol preference) as plain text.

How It Works¶

Built with Cloudflare Pages and a single Function (functions/\[\[path]].js).
Uses the CF-Connecting-IP header to detect the client’s public IP.
Returns plain text for simplicity and expanded use cases.

Notes¶

This service returns only the IP used for the connection (IPv4 or IPv6), not both simultaneously. For a dual-IP display, check out https://ipcow.com/. No external dependencies—just pure Cloudflare magic. Use at your will, no guarantees implied.
