netlupaIP address lookup
Enter a public IP to see its country, approximate city and the company that runs it.
How to look up an IP
Type or paste the IP address, IPv4 or IPv6. If you open the page without one, your own IP is suggested.
Click “Look up” to query the geolocation database.
Check the country, city and provider. From there you can jump to WHOIS to see who manages the range.
How does IP geolocation work?
IP address blocks are allocated to providers and companies by the regional internet registries (RIPE in Europe, ARIN in North America, LACNIC in Latin America…). Geolocation databases combine those records with information published by the providers themselves, latency measurements and usage data to estimate where each range is used.
That is why the country is very reliable, the region fairly reliable and the city only approximate: it often matches the provider's hub rather than the place where the device actually is.
What do ISP and ASN mean?
The ISP (Internet Service Provider) is the company that gives that IP access to the internet: a home broadband provider, a cloud provider, a university… The ASN (Autonomous System Number) identifies that company's network on the internet, for example AS7922 or AS15169. It is the most reliable way to know who an IP belongs to, far more than the city.
Common uses
- Checking where someone signed in to one of your accounts from.
- Reviewing the origin of a suspicious email or of attacks in a server's logs.
- Confirming that a VPN gives you an IP in the country you expect.
- Figuring out why a website shows you content meant for another country.
Why the location sometimes looks wrong
If the tool places an IP in another city, or even another country, there is almost always a technical reason:
- Mobile data: carriers route the traffic of millions of phones through a handful of points in their network, so the IP shows up in the city where that point is, not where you are.
- CGNAT: if your provider shares one IP among many customers, the location is that of the shared network.
- VPNs, proxies and private relays: the IP belongs to the server you connect through, which can be in any country.
- Recently transferred blocks: when an IP range changes owner or country, databases take a few weeks to catch up.
- Corporate and cloud networks: IPs from Amazon, Google or Microsoft are placed in their data centers, even when the service is used by someone on another continent.
For important decisions (blocking access, detecting fraud), combine the IP's country with other signals and do not rely on the city.
Frequently asked questions
Is an IP's location accurate?
No. The country is right almost every time, but the city is approximate and can be tens of miles away. With mobile or VPN IPs the error is even larger.
Why doesn't a private IP have a location?
Private IPs (10.x.x.x, 172.16-31.x.x, 192.168.x.x) are reused in millions of home and office networks, so they do not identify any place. Only public IPs can be located.
Can I look up an IPv6 address?
Yes. The tool accepts both IPv4 and IPv6 addresses.
Is it legal to look up an IP?
Yes. Geolocation data is public and approximate: it points to a provider's network, not to a person. Only the provider can identify who holds a connection, and only under a court order.
What if my IP shows up in another city?
That is normal: the location is that of a point in your provider's network, which may be in another region. If a website shows you content for the wrong country, try turning off your VPN or private relay, or ask your provider to review the registration of its range.
Can I locate someone who sent me an email?
Many email services, such as Gmail, do not include the sender's IP in the headers. When it does appear, it only points to the provider's or mail server's network, not to where the person is.
