What is my IP — and is my connection safe?
Your public IP, ISP/ASN and approximate location, read from this request. We also flag CGNAT and show which DNS resolver you are using, computed entirely from the request with nothing stored and no third-party geolocation database queried at any point.
Next step
See if this IP shows up on a mail blocklist, check which ports are open on it (with your consent), or confirm which DNS resolver your connection actually uses.
How it works and limits
The address above comes straight from the connection this page is served over: the CF-Connecting-IP header and the
network metadata (ASN, approximate location, protocol) Cloudflare attaches to the request. Nothing is looked up from a
third-party geolocation database and nothing about the request is stored — the response is served with
Cache-Control: no-store.
What the CGNAT hint means
If your result shows the shared-IP hint, it is based on one of two signals: your address falls in the IANA Shared
Address Space (100.64.0.0/10, RFC 6598) reserved for carrier-grade NAT, or your network’s ASN organisation name
matches a short list of known mobile carriers. Both are best-effort hints, not certainties — a shared IP means other
customers on the same ISP or carrier can appear to share “your” address, which matters if a later check (such as a
blacklist or port scan) comes back positive: the result may belong to someone else on the same IP.
Limits
- Location is approximate (city/region level at best) and comes from Cloudflare’s network data, not GPS.
- A dynamic IP can change at any time; this page only shows the address for the current request.
- This page cannot force a second, IPv6-only connection to check IPv6 reachability independently — see the IPv6 check panel above for why, and what it shows instead.
Frequently asked questions
Does checking my IP store anything?
No. The result is computed from the request and the response is served with Cache-Control: no-store; see /legal/privacy/.
Why does my IP look different from my router's IP?
Most ISPs do Network Address Translation (NAT): your devices share one public IP. If several unrelated households share the same public IP, that is CGNAT, which this tool flags as a hint.
