About IPconf
IPconf is a free, no-signup tool and API for checking your public IP, looking up geolocation, and running everyday network diagnostics — DNS, ping, traceroute, SSL, WHOIS, HTTP headers, port scans, and more.
What you can do here
- Check your public IP in the browser, or directly from
the command line:
curl https://ipconf.mereturns plain text,curl https://ipconf.me/jsonreturns full geolocation. - Look up any IP — country, region, city, ISP, ASN, and
timezone. Names available in English and Chinese
(
?lang=zh). - Run network diagnostics against any host: DNS (A / AAAA / MX / TXT / CNAME / NS), ping, traceroute, SSL certificate inspection, HTTP headers, blacklist check, ASN/WHOIS, port scan, CDN detection, DNS leak test.
- Use the REST API for anything you can do in the UI. Public IP endpoints are free with no key; tool endpoints require a lightweight client key for rate limiting only. See API docs.
Built for developers
We picked design choices a developer would pick. The root domain returns
plain text to curl / wget / scripted clients,
and HTML to browsers — so you can pipe the result into a shell variable
without parsing. The JSON endpoint is a flat object you can pipe through
jq or any HTTP client. Tool endpoints all share the same
POST /api/tools/<name> shape with a JSON body. No
sign-up, no email verification, no dashboards to navigate.
Data sources and accuracy
Geolocation is built on MaxMind GeoLite2 (country, city, ASN), with manual calibration for Chinese carrier blocks and a user-driven correction queue. Country-level accuracy is typically >95%; region- and city-level accuracy is best-effort and noticeably weaker for mobile carriers running CGN, large enterprise networks, and any cloud / VPS IP. Treat the data as a hint, not an identity claim.
If something looks wrong on a specific IP, the result page has a Report button that queues a correction we review and apply within a few hours.
Privacy
We don't require accounts. We don't profile visitors across sessions. Browser-side analytics is limited to either Google Analytics or Baidu Analytics (whichever your region uses), and you can opt out by blocking the analytics domain. Server logs of your IP are kept for at most 30 days for abuse prevention and aggregate statistics. See our privacy policy for the full details.
Two domains, one service
- ipconf.me — English UI, served from a global Cloudflare edge.
- ipconf.cn — Chinese UI, optimized for visitors in mainland China.
Both domains share the same backend API
(api.ipconf.me) and the same data, so the answer you get is
identical regardless of which one you query.
