IP geolocation lookup: find location, ISP, and ASN for any IP
An IP geolocation lookup shows you the country, region, city, ISP, ASN, and approximate coordinates for any IPv4 or IPv6 address in seconds. Use the free ToolHQ IP geolocation lookup to look up any IP address now.
An IP geolocation lookup is a network tool that queries a geolocation database to return the geographic and network information associated with an IP address, including its approximate location, the organization or ISP that owns it, and its Autonomous System Number (ASN).
IP addresses are assigned by regional internet registries to ISPs, businesses, cloud providers, and governments. Each assignment includes metadata about the owner and their location. Geolocation tools map that metadata to geographic coordinates and display it in human-readable form. This information is useful for security analysis, traffic analysis, debugging network issues, and understanding where requests or traffic originate.
Key takeaways
- Returns country, region, city, ISP, ASN, and approximate coordinates for any IP
- Works on both IPv4 and IPv6 addresses
- Only the IP address you enter is queried, no personal data is stored
- Useful for security analysis, server log review, and network debugging
- Free, instant, no account required
What IP geolocation is and how it works
Every device connected to the internet has an IP address (Internet Protocol address). IPv4 addresses are 32-bit numbers written in dotted decimal form (e.g., 203.0.113.45). IPv6 addresses are 128-bit numbers in hexadecimal form (e.g., 2001:db8::1). Both are allocated by Regional Internet Registries (RIRs) to organizations in specific geographic regions.
IP geolocation works by cross-referencing an IP address against several data sources:
- WHOIS records: registration data showing which organization was allocated an IP range
- BGP routing tables: which ASN (Autonomous System Number) announces the IP prefix
- Geolocation databases: maintained by companies that track IP-to-location mappings through network measurement, user reports, and commercial data sources
The result is an estimate, not a precise location. Residential and mobile IP addresses are typically located to the city level with reasonable accuracy. Cloud provider and VPN IP addresses may show the provider's data center location rather than the user's actual location. Enterprise and corporate IPs often show the company's headquarters rather than the specific office.
The data returned by a geolocation lookup includes:
- Country and region: ISO country code and regional subdivision
- City: approximate city associated with the IP block
- ISP/Organization: the name of the internet service provider or company that owns the IP range
- ASN: the Autonomous System Number, a globally unique identifier for the network operator
- Coordinates: approximate latitude and longitude for the IP block
When IP geolocation lookup is useful
Analyzing web server access logs. When reviewing server logs for unusual traffic, geolocation lookup tells you where requests originated. A spike in traffic from a specific country or ISP may indicate a bot campaign, DDoS attempt, or a marketing effort that drove unexpectedly high traffic from a region.
Security incident analysis. If a login attempt, spam submission, or suspicious API call appears in your logs, looking up the source IP shows you the ISP and location. Combined with pattern analysis, this helps distinguish automated attacks from human users.
Troubleshooting geolocation-based features. If your application uses geolocation to deliver localized content or pricing, a lookup on specific IP addresses helps verify that the IP-to-location mapping is producing the results you expect.
Network debugging and API testing. Developers building applications that accept requests from different regions use geolocation lookups to verify that traffic is routing through the expected networks.
Content distribution verification. CDNs and proxy services route traffic through distributed infrastructure. Checking the geolocation of specific IP addresses confirms which CDN edge server or proxy is handling requests from a given region.
Mini-story: David, a 38-year-old security engineer at a fintech company in London, was reviewing an overnight batch of failed login attempts in the application logs. He isolated a set of 200 attempts from IP addresses he did not recognize. He ran a sample through the ToolHQ IP geolocation lookup and found they all resolved to the same ISP and ASN in a country the company had no customers in. The ASN was flagged in public threat intelligence databases as a known VPN exit node operator. He used this information to implement a temporary block on that ASN at the firewall level, reducing the attack surface while the security team investigated further.
How to use the IP geolocation lookup: step by step
Enter an IP address. Type or paste the IPv4 or IPv6 address you want to look up. Both formats are supported. You can also look up your own current IP address without entering anything, as many tools auto-detect it.
Run the lookup. The tool queries the geolocation database and returns results immediately.
Review the location data. The output shows country, region, city, ISP, ASN, and approximate coordinates. Note that the city-level accuracy varies. Some IP ranges are mapped precisely to a city; others are mapped only to a country or region.
Check the ISP and ASN. The ISP name and ASN provide the most reliable data. An IP from "Amazon AWS" in a US-East region is unambiguously a cloud server, regardless of the city shown. An IP from a residential broadband ISP with a city in Germany tells a different story.
Use the coordinates carefully. The latitude and longitude returned by geolocation tools are block-level estimates, not precise addresses. Do not use them to draw conclusions about specific individuals.
Tips for working with IP geolocation data
Treat city-level data as an approximation. Most geolocation databases are accurate to the country and ISP level. City-level accuracy varies from very high for some IP blocks to completely wrong for others (particularly for mobile IPs and VPN addresses). Never rely on city-level IP geolocation for high-stakes decisions.
ASN is the most reliable data point. The Autonomous System Number identifies the network operator with high confidence. Knowing that an IP belongs to Google, AWS, Comcast, or a specific mobile carrier is actionable information even when city-level data is imprecise.
VPN and proxy IPs show the exit node location, not the user. If a user is behind a VPN, the IP geolocation shows the VPN provider's exit node location, not where the user actually is. This is relevant for both security analysis and geographic access control.
IPv6 addresses may return less precise data. Geolocation databases for IPv6 are generally less mature than for IPv4. Country and ISP data are usually reliable, but city-level data may be missing or less accurate.
Mini-story: Sofia, a 27-year-old data analyst in São Paulo, was troubleshooting why users in Brazil were being served English-language content instead of Portuguese. She pulled a sample of Brazilian user IP addresses from the analytics platform and ran them through the ToolHQ IP geolocation lookup. The data showed that several of those IP addresses resolved to US-based data centers rather than Brazil. The users were accessing the site through a corporate VPN that tunneled all traffic through a US gateway. The geolocation logic was working correctly; the apparent Brazil traffic was actually routing through the US. The fix was to add user-preference language selection rather than relying solely on IP geolocation.
The what-is-my-IP tool shows your own public IP address and its geolocation. The DNS lookup tool resolves domain names to IP addresses, which you can then look up in the geolocation tool.
Frequently asked questions
How accurate is IP geolocation?
Country-level accuracy is typically 95-99% for IPv4 addresses. City-level accuracy ranges from very high for fixed residential broadband to low or wrong for mobile, VPN, and cloud provider addresses. ASN and ISP data is highly reliable.
What is an ASN?
An ASN (Autonomous System Number) is a globally unique identifier assigned to a network that independently routes internet traffic. Examples include AS15169 (Google), AS16509 (Amazon AWS), and AS3215 (France Telecom). The ASN identifies who operates the network, regardless of geography.
Can IP geolocation identify a specific person?
No. IP geolocation identifies the organization that owns an IP address and its approximate location. It cannot identify a specific person or precise address. For residential IPs, the information shows the ISP's local infrastructure location, not the user's home address.
Does the lookup work for IPv6 addresses?
Yes. The tool accepts both IPv4 (e.g., 203.0.113.45) and IPv6 (e.g., 2001:db8::1) addresses. IPv6 geolocation data is generally less precise than IPv4 at the city level but reliable at the country and ISP level.
Is my data stored when I use the lookup?
Only the IP address you enter is queried. No personal information is collected or stored.
Why does a geolocation lookup return no results for some IP addresses?
Some IP address ranges are reserved for private networks and are never used on the public internet. Common private ranges are 192.168.0.0/16 (home and office LANs), 10.0.0.0/8 (enterprise networks), and 172.16.0.0/12 (also private). These are called RFC 1918 addresses. If you copy an IP from your local network's settings or a server's internal log and it falls into one of these ranges, there is no public geolocation record for it because it is not routable on the internet. Similarly, the loopback address 127.0.0.1 always refers to the device itself. To find your public IP address (the one the internet sees), use ToolHQ's What Is My IP tool instead.
The short version
An IP geolocation lookup reveals where an IP address is located, which ISP owns it, and what ASN it belongs to. ToolHQ's free tool handles both IPv4 and IPv6, requires no account, and only queries the IP address you enter.
