IP Address Lookup
Trace Any IP Address with Our Geolocation Lookup Tool
Instantly find the geographic location and network details of any public IP address with our free IP Lookup tool. Whether you're a network administrator investigating traffic, a developer testing an application, or just curious about the origin of a connection, this tool provides key information including the country, city, ISP, and an approximate location on a map.
About the IP Lookup Tool
The IP Address Lookup tool queries global GeoIP databases to provide detailed information about any public IPv4 or IPv6 address. By entering an IP, you can determine its approximate geographic location, the Internet Service Provider (ISP) that owns the address block, the assigned hostname, and other network details. This utility is essential for network administrators, cybersecurity professionals, and anyone needing to investigate network connections, verify the location of a server, or identify the provider of a specific IP address.
How to Use the Tool and Interpret the Results
Our tool provides a simple interface to a wealth of public data.
Using the IP Lookup Tool
- Enter an IP Address: Type or paste the public IPv4 or IPv6 address you wish to investigate into the input field.
- Click "Lookup IP": The tool will send a query to our backend service, which in turn gathers data from a GeoIP database.
- Review the Information: The results will be displayed in a clear table format, showing the location, provider, and other network details. If coordinates are available, a map will also show the approximate location.
Interpreting the Results
- Geolocation (Country, City): This shows the registered location of the IP address block. It's generally accurate to the country and city level, but it is not a precise street address.
- ISP (Provider): This is the Internet Service Provider or organization that owns and manages the IP address block.
- Hostname: This is the reverse DNS (rDNS) name associated with the IP address, often assigned by the ISP.
- Coordinates & Map: The latitude and longitude provide a point for the map, visualizing the city-level location of the IP.
A Guide to IP Address Lookups and Geolocation
Every device connected to the public internet is assigned an IP address, which acts like a postal address for sending and receiving data. IP lookup and geolocation are the processes of using this public address to determine information about its network and location.
How Does IP Geolocation Work?
IP geolocation is not a real-time tracking system. Instead, it relies on databases that associate IP address blocks with specific locations. Here’s how the data is compiled:
- IP Address Allocation: Global authorities like IANA allocate large blocks of IP addresses to Regional Internet Registries (RIRs).
- Distribution to ISPs: The RIRs then assign smaller blocks to ISPs and large organizations within their geographic regions.
- Database Mapping: Third-party data providers aggregate this public registration data and use other methods (like network latency and traceroute data) to build databases that map these IP blocks to the countries, regions, and cities where the ISPs operate.
When you use our lookup tool, it queries one of these databases to find the record associated with the entered IP address.
Accuracy and Limitations
It's important to understand the limitations of IP geolocation:
| Level of Accuracy | Typical Reliability | Explanation |
|---|---|---|
| Country | Very High (~99%) | IP blocks are officially assigned to entities within a specific country. |
| Region / State | High (~90%) | ISPs often use regional IP blocks, making this data fairly reliable. |
| City | Moderate (~70-80%) | The location often points to the ISP's central office or point-of-presence in a city, not the user's home. Accuracy can vary greatly, especially in rural areas. |
| Street Address | Extremely Low / Not Possible | Public databases do not contain personal subscriber information or street-level addresses. |
Because IP geolocation is not precise, and because users can mask their true IP with services like VPNs and proxies, you should never rely on IP lookup data to make definitive judgments about an individual's identity or exact location.
Common Use Cases
- Content Localization: Websites and streaming services use IP geolocation to serve country-specific content, languages, and pricing.
- Cybersecurity: Security analysts use IP lookups to identify the origin of suspicious traffic, block connections from high-risk regions, and investigate security incidents.
- Fraud Detection: E-commerce and financial services use IP location as one of many signals to detect potentially fraudulent transactions.
- Network Troubleshooting: Engineers use lookups to verify that traffic is being routed through the expected geographic paths.
While online lookup tools are excellent for quick checks, professionals in cybersecurity and fraud detection often subscribe to commercial GeoIP databases or APIs that provide more detailed data and higher query volumes for automated analysis. For legal investigations, data must be formally requested from the ISP through proper legal channels.
Frequently Asked Questions about IP Lookups
What is an IP lookup?
An IP lookup is a process that queries public databases to find information associated with a specific IP address. This typically includes its geographic location (country, region, city), the Internet Service Provider (ISP) that owns the address, and the hostname, if available.
How accurate is IP address geolocation?
IP geolocation accuracy varies. It is generally very accurate at the country level. At the city level, it is reasonably accurate but should be considered an approximation, not a precise street address. The location data points to the location of the ISP's network equipment, not the user's physical home.
Can an IP lookup reveal my personal identity?
No, a public IP lookup tool cannot reveal your personal identity, name, or street address. It only shows information associated with the IP block, such as the ISP and general location. Only law enforcement, with a legal warrant, can request specific subscriber information from an ISP.
How do I use this IP lookup tool?
Simply enter any public IPv4 or IPv6 address into the input field and click the 'Lookup IP' button. The tool will display the geolocation data and network information for that address.
What is an ISP?
ISP stands for Internet Service Provider. It is the company that provides you with access to the internet (e.g., Comcast, AT&T, Verizon, Spectrum).
Can I look up my own IP address?
Yes. To find your own public IP address and its associated information, you can use our dedicated What's My IP? tool.
What does 'hostname' mean in the results?
The hostname is a human-readable label assigned to a device (or IP address) on a network. For public IPs, this is often a generic name assigned by the ISP that may include location or network codes (e.g., `cpe-123-45-67-89.city.state.comcast.net`).
Why would I want to look up an IP address?
You might look up an IP address to investigate the source of an email, analyze web server traffic logs, check the location of a server you're connecting to, or report network abuse or suspicious activity.
Can I look up a private IP address like 192.168.1.1?
No, private IP addresses (like those in the 192.168.0.0/16, 172.16.0.0/12, or 10.0.0.0/8 ranges) are not unique and are not routable on the public internet. Therefore, they cannot be looked up in public geolocation databases.
What is the difference between an IP lookup and a WHOIS lookup?
An IP lookup primarily provides geolocation data. A WHOIS lookup provides the registration data for an IP address block, including which organization owns it and their contact information for network abuse reports.
What do the latitude and longitude represent?
The latitude and longitude are the geographic coordinates for the approximate location of the IP address, typically the center of the city associated with that IP block.
Can I hide my IP address?
Yes, you can hide or mask your real IP address by using a Virtual Private Network (VPN) or a proxy server. These services route your traffic through their own servers, making it appear as though you are connecting from the server's location.
Are the results for IPv4 and IPv6 lookups different?
The type of information provided is generally the same for both IPv4 and IPv6 lookups: geolocation, ISP, and organization. However, the specific data will, of course, correspond to the respective IP address.
Why does the location for my mobile device's IP change?
Mobile devices often get IP addresses from a pool that is routed through the mobile carrier's central network gateways. The IP's registered location may be that of the gateway, which could be in a different city than your actual physical location.
What is an Autonomous System (AS)?
An Autonomous System is a large network or group of networks that has a single, unified routing policy. Each ISP, large tech company, or university typically has its own AS, identified by an Autonomous System Number (ASN).
What does it mean if an IP is listed as a proxy or VPN?
Our tool can sometimes detect if an IP address belongs to a known VPN provider, proxy service, or Tor exit node. This indicates that the user's true IP address is likely being masked.
How often is IP location data updated?
The databases that map IPs to locations are updated regularly by data providers. However, there can be a lag between when an ISP reassigns an IP block to a new area and when the databases are updated.
Can I find out who is using a specific IP address right now?
No, a public lookup tool cannot tell you the specific person or device using a dynamic IP address at any given moment. Only the ISP that owns the address has that information in their logs.
What if an IP lookup shows the wrong country?
While rare, this can happen if the IP address block was recently transferred from an organization in one country to another and the database has not yet been updated. It can also happen with satellite internet services where the ground station is in a different country.
Can I use this tool for legal purposes?
This tool is for informational purposes only. The data provided should not be used as sole evidence in legal proceedings. For legal matters, official records must be obtained directly from the ISP through proper legal channels.
What is DNS?
DNS (Domain Name System) is what translates a website name (like www.google.com) into an IP address. You can investigate a domain's DNS records with our DNS Lookup tool.
How does a website know my IP address?
Your public IP address is included in the header of every packet your computer sends over the internet. Web servers read this source IP address to know where to send the response (i.e., the website content).
Is my IP address permanent?
For most residential internet users, your public IP address is dynamic, meaning your ISP can change it from time to time. Businesses can often request a static (permanent) IP address for an additional fee.
Can I be tracked by my IP address?
Your IP address can be used to track your online activity by websites, advertisers, and your ISP. This is a primary reason why people use VPNs for enhanced privacy.
Do I need a professional to interpret IP lookup results?
For general interest, the results are straightforward. For business purposes, such as cybersecurity incident response or network forensics, a qualified IT or security professional is needed to correctly interpret the data in the context of other evidence and take appropriate action.
