What Is an IP Address Lookup?
An IP Address Lookup retrieves information associated with an IP address from an IP intelligence service. Depending on the address and available data, results can include country, region, city, internet service provider, network organization, autonomous system number, and timezone.
This tool supports public IPv4 and IPv6 addresses. The information returned depends on the external lookup provider and may not include every field for every address.
What Information Can You Find?
- IP version: Identify whether the address uses IPv4 or IPv6.
- Geolocation: View the reported country, region, city, postal code, and coordinates when available.
- ISP and organization: See the internet service provider or network organization associated with the address.
- ASN: Inspect the reported autonomous system number when available.
- Timezone: Review the timezone identifier, UTC offset, and local time when provided.
- Network indicators: View available VPN, proxy, Tor, or hosting indicators when supported by the lookup service.
- Raw response: Inspect and copy the JSON returned by the service.
IPv4 vs. IPv6
IPv4 addresses use a 32-bit address format, commonly written as four decimal numbers separated by periods, such as 8.8.8.8. IPv6 uses a 128-bit format represented with hexadecimal groups separated by colons.
This tool accepts both formats. The address version is identified from the input and displayed with the lookup results.
How to Use the IP Address Lookup Tool
- Enter a valid IPv4 or IPv6 address.
- Click Lookup IP or choose one of the example addresses.
- Review the available location, network, ISP, and timezone information.
- Copy the results or inspect the raw JSON response for troubleshooting.
How Accurate Is IP Geolocation?
IP geolocation provides an approximate indication of where an IP address or network may be located. It does not reliably identify a person's exact physical location or home address.
VPNs, proxies, mobile networks, corporate gateways, and internet routing can affect results. Use IP lookup data as a reference rather than definitive proof of a person's identity or location.
Privacy and External Lookup Services
The entered IP address is sent to an external lookup service to retrieve the requested information. Avoid submitting sensitive data, and review the provider's privacy policy and usage limits before relying on the service for high-volume applications.
The tool reports the data returned by the provider; it does not independently verify the ownership, identity, or security of an IP address.
Frequently Asked Questions
▶Is this IP Address Lookup tool free?
Yes. ToolTunnel provides the tool free of charge. Lookups rely on an external API that may apply usage limits or availability restrictions.
▶Can I look up both IPv4 and IPv6 addresses?
Yes. The tool accepts valid IPv4 and IPv6 address formats and displays the information returned by the lookup service.
▶Can an IP lookup find someone's exact address?
No. IP geolocation is approximate and generally provides network-level location information. It does not reliably reveal a person's exact physical address.
▶What is an ISP in an IP lookup?
ISP stands for Internet Service Provider. The lookup service may identify the provider or organization associated with the network using the queried IP address.
▶What is an ASN?
An Autonomous System Number identifies a network or group of IP routing prefixes managed under a common routing policy. Lookup services may return an ASN and its associated organization.
▶Why is the IP location incorrect?
IP location databases can be approximate or outdated. VPNs, proxies, mobile carriers, corporate networks, and routing arrangements can cause the reported location to differ from the user's actual location.
▶Can I look up a private IP address?
The tool can validate the address format, but private and reserved IP addresses generally do not have public geolocation information. The external service may return an error or limited results for these addresses.
▶Does this tool perform a security scan?
No. It displays the information returned by the IP lookup service. Any available VPN, proxy, Tor, or hosting indicators are informational and do not constitute a comprehensive security scan.
