Free IPv4 and IPv6 IP lookup
Use this free IP lookup tool to check your own IP automatically, or search any IPv4 or IPv6 address to see network ownership and approximate location on a map.
We’re detecting your IP now. You can also enter any IPv4 or IPv6 address for a free IP lookup with country, region, latitude/longitude, provider, ISP, organization, ASN, and network range.
IP address reference
An IP address is the public network address used to route traffic across the internet. When you look up an address, IP Atlas compares it with known network ranges and returns practical routing context: the country, region, city, autonomous system number, provider, ISP, organization, and approximate latitude and longitude when those fields are available.
This information is useful for website analytics, security reviews, localization, fraud signals, network troubleshooting, abuse triage, and understanding why traffic appears to originate from a specific provider or geography. The result describes a network endpoint, not a verified person, household, or device.
IPv4 addresses use four decimal numbers, such as 8.8.8.8. IPv6 addresses use hexadecimal groups, such as 2001:4860:4860::8888. IP Atlas supports both formats so you can compare older IPv4 routing data with modern IPv6 network allocations.
Read the IP address guideAn ASN identifies the autonomous system announcing a route. Provider, ISP, and organization labels usually point to the network operator, hosting company, access provider, or business entity associated with that range.
Understand network fieldsIP geolocation can identify a likely city, region, routing hub, data center, or provider footprint. It should be treated as an estimate and combined with other signals when accuracy matters.
Learn about accuracyUse IP lookup data as network intelligence. It can help flag unusual traffic patterns, choose a regional default, or explain provider ownership, but it should not be used to identify a specific person or exact street address. Mobile carriers, VPNs, corporate gateways, cloud providers, and content delivery networks can all shift the apparent location away from the person using the connection.
