À propos de cet outil
Every device on the internet has an IP address, and that address quietly says a fair amount: roughly where it is, which network owns it, and which company routes its traffic. This tool resolves any IPv4 or IPv6 address to its country, city and region, the ISP and organisation that own the block, the autonomous system (ASN) number, the local timezone, and the reverse DNS hostname if one is published. Leave the box empty and it looks up the address you are connecting from. Unlike most tools on this site, the lookup runs on our server rather than in your browser - geolocation providers cannot be called directly from a web page - so the address you submit is sent to us, used for the lookup and then discarded. There is a daily limit so the free service stays available to everyone.
Comment utiliser cet outil
- Enter an IP addressIPv4 like 8.8.8.8 or IPv6 like 2001:4860:4860::8888. Leave it empty to look up your own.
- Run the lookupPress Look up or hit Enter. The answer usually comes back in well under a second.
- Read the network ownerThe ISP, organisation and ASN tell you who actually operates the address block.
- Check the reverse DNSA PTR hostname often reveals the hosting provider or data centre, when one is published.
- Treat the location as approximateIt comes from registration records, so it is usually right to the city or region and never a precise position.
Pourquoi l’utiliser
- Handles both IPv4 and IPv6, not just IPv4.
- Shows the ASN and organisation, which identify the real network operator rather than only a city.
- Includes reverse DNS in the same lookup, so you do not need a second tool.
- Looks up your own address when you leave the field empty.
- States plainly that the location is an estimate rather than presenting it as a precise position.
- Free with no account, and a visible daily allowance so you always know where you stand.
Usages courants
- Checking which country and provider an unfamiliar address in your server logs belongs to.
- Confirming a VPN is actually presenting the country you selected.
- Identifying the hosting company behind a site or a bot.
- Working out the local timezone of a visitor or a server.
- Sanity-checking a firewall or geo-blocking rule before you rely on it.
Conseils pour de meilleurs résultats
- The ASN is the most reliable field. City-level data is estimated, but the network owner is a matter of public registration record.
- A reverse DNS name often gives away the host - names containing amazonaws, googleusercontent or ovh are a strong hint.
- If the city looks wrong, that is normal. Many providers register whole blocks to a single head-office address.
- Private addresses such as 192.168.x.x or 10.x.x.x have no public location by design, and the tool will say so.
Erreurs à éviter
- Treating the coordinates as a device location. They identify a network, not a person or a house.
- Assuming an IP identifies one individual. Mobile networks and shared connections put thousands of people behind a single address.
- Blocking a whole country by IP and expecting it to hold - VPNs and proxies make that trivially avoidable.
- Looking up a private address and reading "no location" as a failure. It is the correct answer.
Questions fréquentes
Country level is usually reliable. City level is often right but frequently off by a considerable distance, because providers register large blocks to one administrative address. It is an estimate derived from registration and routing data, never a device position, and should never be treated as one.
No, and the page says so. Geolocation providers cannot be called from a web page - the request would be blocked and any key would be exposed - so the lookup happens on our server. The address you submit is used for the lookup and then discarded; it is not stored.
Each lookup makes a call out from our server, so the tool has a per-visitor daily allowance and a site-wide ceiling. The remaining count is shown on the page. The limits exist so the tool stays free and available rather than being drained by automated use.
Yes. Paste it in the same box - both IPv4 and IPv6 are supported, and the result tells you which one it recognised.
An Autonomous System Number identifies the network that routes an address block, usually an ISP, hosting company or large organisation. It is the most dependable field here, because it comes from public routing registration rather than estimation.
Addresses like 192.168.1.1, 10.0.0.5 or 127.0.0.1 only exist inside a local network, so they are not routable on the public internet and have nothing to geolocate. That is correct behaviour, not an error.
No, and you should be wary of any tool that claims otherwise. An IP maps to a network, not a person or a building. Only the ISP holds subscriber details, and they release them only to a lawful request.
