The IP checker is a tiny utility with one job: tell you the IP address. Yours, or whatever IP a website is currently resolving to. Open it at checkmyipaddress.net ↗.

​
What it does

Two modes:
  • Visit it in a browser. The page returns your public IP, your reverse DNS, your ASN, and the country your IP geolocates to. Useful when you need your IP for a firewall whitelist and don’t trust the network you’re on.
  • Hit it with cURL. A plain-text endpoint at the same address returns the bare IP, nothing else. Easy to chain into shell scripts.
$ curl checkmyipaddress.net
203.0.113.42
For checking a website’s IP rather than your own, the page accepts a hostname and returns the A and AAAA records the public DNS hands out for that name.

​
When to reach for it

  • Firewall whitelisting. Your IP changes when you switch networks. The checker tells you what the firewall actually sees.
  • Cloudflare debugging. If a site is on Cloudflare, the public DNS returns a Cloudflare edge IP, not the origin. Compare what the checker returns against what your origin server actually has; if they match, the site is bypassing Cloudflare and orange cloud isn’t doing its job.
  • Verifying a DNS change propagated. Run the checker, see what IP the public DNS returns; if it’s the new one, propagation is done from your network’s perspective. If it’s still the old one, your local resolver is caching.
  • Quick scripting. Anything that wants the local public IP at runtime can grab it with curl checkmyipaddress.net and trust the answer.
