IP Geolocation Lookup

Your IPv4: Not detected

Your IPv6: Not detected

What Is IP Geolocation Lookup?

IP geolocation lookup is the process of determining the approximate physical location of a device using its Internet Protocol (IP) address. By querying geolocation databases, you can identify the country, city, ISP, timezone, and coordinates associated with any IPv4 or IPv6 address — without installing any software.

Every device connected to the internet is assigned an IP address by its Internet Service Provider. This address serves as a digital identifier, and because IP addresses are allocated in geographic blocks, it is possible to map them to real-world locations with reasonable accuracy. IP geolocation is the technology behind this mapping, and it powers everything from content localization to fraud detection.

Our free IP lookup tool lets you instantly retrieve geolocation data, network details, and security intelligence for any public IP address. Simply enter an IP address above to get started — results appear in seconds.

How Does IP Geolocation Work?

IP geolocation relies on a layered system of internet infrastructure and data collection. At the foundation are the five Regional Internet Registries (RIRs) — ARIN (North America), RIPE NCC (Europe and Middle East), APNIC (Asia-Pacific), AFRINIC (Africa), and LACNIC (Latin America) — which allocate IP address blocks to ISPs and organizations within their regions. These allocation records form the first layer of geolocation data.

The Border Gateway Protocol (BGP) adds another layer by revealing how IP address blocks are routed across the internet. Each block is announced by an Autonomous System (AS), which is a network operated by a single organization. You can explore these relationships using our ASN Lookup tool, or check registration details with WHOIS Lookup.

Geolocation databases compile data from RIR records, BGP routing tables, active network measurements, and user-contributed corrections to build comprehensive mappings between IP addresses and physical locations. Our tool cross-references two leading databases — MaxMind GeoLite2 and DB-IP — using a composite approach. When both sources agree on a location, the result carries higher confidence. When they differ, our system intelligently merges the data to provide the most complete and accurate result possible.

What Data Does an IP Lookup Reveal?

A comprehensive IP lookup returns far more than just a city and country. Our tool organizes results into three clear categories, giving you a complete picture of any IP address.

IP Details

The core identity of an IP address includes the address itself (IPv4 or IPv6), its decimal equivalent, and the reverse DNS hostname. You will also see the IP type classification — whether the address belongs to a residential connection, a datacenter, a VPN provider, a Tor exit node, or a proxy service. This classification is essential for understanding the nature of the traffic behind an IP.

Location

Geolocation data includes the country (with flag), region or state, city, postal code, geographic coordinates (latitude and longitude), timezone, continent, currency, and international calling code. Together, these fields paint a detailed geographic profile of where an IP address is physically located.

Network

Network information reveals the ISP or hosting provider, the organization that owns the IP block, the Autonomous System Number (ASN), the Regional Internet Registry responsible for allocation, the date the IP block was first allocated, and the abuse contact for reporting issues. This data is invaluable for network administrators and security professionals.

Verified users gain access to premium intelligence fields including threat scoring, VPN and Tor detection, proxy identification, sanctions status checks, and economic indicators for the associated country.

Common Use Cases

Content Localization

Websites use IP geolocation to deliver region-specific content, language preferences, and local currency pricing. By detecting a visitor’s country and city, businesses can personalize the user experience without requiring manual input. Pair geolocation with DNS Lookup to verify how your domain resolves in different regions.

Security and Fraud Prevention

Security teams rely on IP geolocation to flag suspicious login attempts from unexpected locations, detect account takeover attempts, and identify traffic from known threat sources. Checking whether an IP appears on threat databases is a key step — our IP Blacklist Check tool automates this across multiple blocklists.

Network Troubleshooting

When diagnosing connectivity issues, knowing the geographic path of network traffic helps pinpoint where problems occur. Use IP geolocation alongside Reverse DNS Lookup and Port Checker to build a complete diagnostic picture of any network path.

Regulatory Compliance

Organizations subject to data residency laws or export controls use IP geolocation to enforce geographic access restrictions. Identifying the origin country of incoming traffic helps ensure compliance with regulations like GDPR, sanctions requirements, and regional licensing agreements.

Digital Advertising

Advertisers use geolocation data to target campaigns by region, verify that ad impressions are served in the intended markets, and detect click fraud originating from unexpected locations. Accurate IP data ensures advertising budgets are spent reaching real users in the right geographies.

How Does IP Geolocation Work?

IP geolocation converts a numeric IP address into a physical location estimate (country, region, city, coordinates) by matching the address against databases of allocated IP ranges. The process runs in five steps:

  1. Receive the IP address The lookup service takes an IPv4 or IPv6 address (for example, 8.8.8.8 or 2001:4860:4860::8888) as input from the request.
  2. Match the IP to an allocated range Regional Internet Registries (ARIN, RIPE, APNIC, LACNIC, AFRINIC) assign IP blocks to ISPs and organizations. The database locates the CIDR range that contains the IP.
  3. Retrieve the location metadata Each allocated range has associated metadata — country, region, city, latitude/longitude, time zone, postal code, and the autonomous system (ASN) responsible for routing.
  4. Cross-reference independent sources This tool queries both MaxMind GeoLite2 and DB-IP. Where one database has a gap, the other fills it in, improving completeness.
  5. Return the enriched result The final response includes location fields, network metadata (ISP, organization, ASN), and optional enrichments (VPN/proxy detection, cloud provider, threat status).

How Accurate Is IP Geolocation?

IP geolocation accuracy varies by level of detail. At the country level, most databases achieve 95-99% accuracy. At the city level, accuracy drops to 50-80% depending on the region, the ISP, and the type of IP address.

This tool cross-references two independent databases — MaxMind GeoLite2 and DB-IP — to improve results. When one database has a gap (missing city, timezone, or postal code), the other fills it in. This composite approach produces more complete and reliable results than relying on a single source.

Accuracy tends to be higher for business and datacenter IPs (which have stable, well-documented allocations) and lower for mobile and residential IPs (where carriers dynamically assign addresses across regions). VPN and proxy IPs reflect the server location, not the user's actual location.

IPv4 vs IPv6: What's the Difference?

IPv4 addresses are the familiar format most people recognize: four numbers separated by dots, like 192.168.1.1. The 32-bit format provides about 4.3 billion unique addresses — a number that seemed enormous in the 1980s but has since been exhausted due to the growth of connected devices.

IPv6 was designed to solve this shortage. Using 128 bits, it provides 340 undecillion addresses (that's 340 followed by 36 zeros). IPv6 addresses look like 2001:0db8:85a3::8a2e:0370:7334. Most modern devices and ISPs support both protocols, and this tool can look up geolocation data for both IPv4 and IPv6 addresses.

You can check which version your device is using by looking at the "Your IPv4" and "Your IPv6" fields at the top of this page. Many connections use both simultaneously through a mechanism called dual-stack networking.

What Do People Ask About IP Geolocation?

How accurate is IP geolocation?
IP geolocation is typically 95-99% accurate at the country level and 50-80% accurate at the city level. Accuracy depends on the database provider, the ISP, and whether the IP is residential or commercial. We use two databases (MaxMind GeoLite2 and DB-IP) and cross-reference them to improve accuracy. Datacenter and business IPs tend to be more accurate than residential or mobile IPs.

Can an IP address reveal my exact location?
No. An IP address shows your approximate location, usually at the city or regional level. It cannot pinpoint your street address or building. The location shown is typically the area served by your ISP, which can be several miles from your actual position. For mobile connections, the location may reflect where your carrier routes traffic, not where you physically are.

What is the difference between IPv4 and IPv6?
IPv4 addresses use 32 bits and look like 192.168.1.1, providing about 4.3 billion unique addresses. IPv6 addresses use 128 bits and look like 2001:0db8:85a3::8a2e:0370:7334, providing a virtually unlimited number of addresses. IPv6 was created because the world is running out of IPv4 addresses. Both can be looked up for geolocation data, and this tool supports both formats.

What can someone do with my IP address?
With just your IP address, someone can determine your approximate geographic location, your ISP, and whether you are using a VPN or proxy. They cannot access your personal files, passwords, or identity. However, your IP can be used for targeted advertising, content geo-blocking, or in rare cases, to attempt denial-of-service attacks. Using a VPN masks your real IP address.

Why does my IP show a different city than where I am?
Your ISP routes your traffic through regional hubs, so your IP geolocation may show the nearest hub city rather than your exact town. Mobile networks and VPNs are especially prone to this. If you are on a company network, the IP may reflect the corporate office location. ISPs also periodically reassign IP blocks to different regions, causing temporary inaccuracies.

What is an ASN (Autonomous System Number)?
An ASN identifies a network or group of IP addresses managed by a single organization, such as an ISP, university, or large company. For example, Google operates AS15169 and Cloudflare operates AS13335. ASN data helps identify who controls an IP address, which network it belongs to, and how internet traffic is routed between networks.

How do I hide my IP address?
The most common ways to hide your IP address are using a VPN (Virtual Private Network), the Tor browser, or a proxy server. A VPN encrypts your traffic and routes it through a server in another location, masking your real IP. Tor bounces your connection through multiple nodes worldwide. Our lookup tool can detect whether an IP is using a VPN, proxy, or Tor exit node. Learn how to verify your VPN is working.

Is IP geolocation legal?
Yes. Looking up the geolocation of a public IP address is legal in most jurisdictions. IP addresses are not considered personal data on their own under most privacy laws, though GDPR treats them as personal data when combined with other identifying information. IP geolocation is widely used by businesses for fraud prevention, content delivery, and compliance purposes.

How often do IP geolocation databases update?
Major providers like MaxMind and DB-IP release database updates weekly or biweekly. However, the underlying data changes gradually since IP block allocations by Regional Internet Registries shift over time as ISPs acquire or release address space. We update our databases regularly to reflect these changes. Some IPs, particularly those recently reassigned between ISPs, may show outdated locations until the next database update.

Can I look up someone else's IP address?
Yes. Any public IP address can be looked up for geolocation data. This is how websites serve region-specific content and how security teams investigate suspicious traffic. You can enter any IPv4 or IPv6 address in the search field above. However, the results will only show approximate location data (city/region level), not a specific person or street address.

What is the difference between a public and private IP address?
A public IP address is assigned by your ISP and is visible to every website you visit. A private IP address (typically starting with 192.168.x.x, 10.x.x.x, or 172.16-31.x.x) is used within your local network and is not routable on the internet. This tool looks up public IP addresses only. To find your private IP, check your device's network settings.

Why does my VPN IP show a different country?
When you use a VPN, your traffic is routed through a server in another location. The IP address visible to websites becomes the VPN server's IP, not yours. This is by design and is the primary purpose of a VPN. Our tool will show the geolocation of the VPN server and will flag the IP as a VPN connection in the IP type field.
