Free IP Address Lookup
Enter any IPv4 or IPv6 address to see its approximate location, ISP, ASN, connection type, and timezone in seconds. Powered by 1Lookup IP intelligence.
IP geolocation is approximate, especially at the city level, and may be inaccurate for mobile, VPN, proxy, or corporate networks. This tool does not reveal a street address or the identity of any individual. Results are provided for informational purposes only and should not be used as the sole basis for any decision affecting a person.
What Is an IP Address Lookup?
An IP address lookup translates a numeric IPv4 or IPv6 address into human-readable context: the approximate city, region, and country, plus the ISP or organization that owns it. Our free IP locator queries up-to-date geolocation, ASN, and routing data so you can understand where traffic originates and which network it belongs to, all without installing software or writing a single line of code.
Behind every IP geolocation result is a blend of data sources: regional internet registry records, BGP routing tables, ASN ownership databases, and observed network behavior. 1Lookup combines these signals to estimate location and identify connection type, whether the IP belongs to a residential broadband line, a mobile carrier, a hosting provider, or a corporate network. The more signals available, the more confident the result.
It is important to be honest about limits. IP geolocation is approximate, especially at the city level, and it never reveals a street address or a person's identity. Use this tool to find an IP location for analytics, fraud review, debugging, and compliance, then upgrade for deeper risk signals like VPN and proxy detection when you need to act on what you find.
How to Look Up an IP Address
Enter an IP address
Paste any public IPv4 (like 8.8.8.8) or IPv6 address into the field. Not sure of yours? Search 'what is my IP' first, then paste the result to geolocate it.
Run the lookup
Click Look Up IP and 1Lookup queries live geolocation, ASN, and threat-intelligence sources in real time, returning a structured result in about a second.
Read and act on the results
Review the city, region, country, ISP, ASN, connection type, and timezone. Sign up free to unlock fraud score, VPN and proxy detection, and accuracy radius.
Approximate geolocation
See the estimated city, region, and country for any IP, with the supporting timezone. Ideal for understanding where visitors, signups, or suspicious requests appear to originate.
ISP, organization, and ASN
Identify the internet service provider or organization that owns the IP and its Autonomous System Number (ASN), so you can tell residential users from data centers and hosting providers.
Connection type detection
Find out whether an IP looks like residential broadband, mobile, business, or hosting infrastructure. Connection type is a fast, reliable signal for distinguishing real users from automated traffic.
IPv4 and IPv6 support
Look up any public address in either format. As IPv6 adoption grows, 1Lookup resolves both protocols against the same intelligence so your results stay consistent.
Who uses this tool
Fraud and risk analysis
Security and fraud analysts geolocate IPs from orders, logins, and signups to spot mismatches, flag hosting-provider traffic, and prioritize reviews. Upgrade for fraud score and VPN/proxy/Tor detection.
Marketing and analytics
Marketers verify the geographic spread of campaign traffic, segment audiences by region, and detect bot or data-center clicks that distort attribution and inflate ad spend.
Server and network troubleshooting
Sysadmins and developers trace where requests, errors, or abuse originate, confirm CDN routing, and decide whether to allow, throttle, or block a given network or ASN.
Compliance and content rules
Teams use country-level geolocation to apply regional licensing, tax, or regulatory logic and to support audit trails, while respecting that IP data is approximate, not definitive.
Frequently asked questions
How accurate is IP geolocation?
IP geolocation is generally reliable at the country level and reasonably accurate for region, but city-level results are only approximate and can be off by tens of miles or land on the wrong nearby city. Accuracy depends on the data the provider has for that network. Mobile, VPN, and corporate IPs are often the least precise.
Can an IP address reveal my exact address or identity?
No. An IP address lookup returns an approximate geographic area and the network owner, not a street address, name, or specific person. Only an internet service provider can link an IP to a subscriber, and typically only under a valid legal request. Treat IP location as a regional estimate, never as personal identification.
What information does this free IP lookup show?
The free result includes the approximate city, region, and country, the ISP or organization, the ASN, the connection type, and the timezone for any IPv4 or IPv6 address. Premium fields, available with a free account, add fraud score, VPN/proxy/Tor detection, threat and abuse history, residential probability, and accuracy radius.
What is an ASN and why does it matter?
An ASN, or Autonomous System Number, identifies the network operator that controls a block of IP addresses, such as an ISP or a cloud host. Knowing the ASN helps you tell residential users from data-center traffic, block abusive networks at scale, and understand how a request actually reaches your servers.
Can I tell if an IP is a VPN or proxy?
The free lookup shows connection type, which hints when an IP belongs to hosting infrastructure often used by VPNs. For explicit VPN, proxy, and Tor detection, plus a fraud score and abuse history, create a free 1Lookup account to unlock those premium intelligence fields on every lookup.
Does it support IPv6 addresses?
Yes. 1Lookup geolocates both IPv4 addresses (like 8.8.8.8) and full IPv6 addresses, resolving each against the same geolocation, ASN, and threat-intelligence sources. As more networks adopt IPv6, you can look up either format and get a consistent, structured result.
Is there an API for bulk IP lookups?
Yes. This page is a free demo of the 1Lookup IP intelligence API. Sign up for 1,000 free lookups, then use the REST API to geolocate IPs programmatically, enrich logs, or process bulk lists with full data including fraud and VPN signals. Rate limits apply to the public tool.
