IP Address Lookup
Look up detailed information about any IP address instantly. This free tool retrieves geolocation data, ISP details, timezone, and network information for both IPv4 and IPv6 addresses. Whether you are identifying the origin of suspicious traffic, troubleshooting network connectivity, configuring geo-based access rules, validating firewall logs, or simply curious about where an IP address is located, this tool provides comprehensive results pulled from accurate IP geolocation databases. Enter any IP address or domain name to get started.
What Is
IP Address Lookup is a powerful online tool that retrieves comprehensive information about any IPv4 or IPv6 address entered into it. When you query an IP address, the tool cross-references multiple authoritative databases to provide geolocation details (country, region, city, postal code, latitude/longitude coordinates), network information (ISP/organization, ASN number, connection type), security insights (whether the IP is associated with a VPN, proxy, Tor exit node, or known malicious actor), and timezone data. This tool is invaluable for web administrators analyzing server logs to identify traffic patterns and potential security threats, developers debugging geolocation features, network engineers troubleshooting routing issues, security professionals investigating suspicious activity, and marketers verifying ad traffic authenticity. The lookup process respects user privacy by not storing queries. Both IPv4 (32-bit, format x.x.x.x) and IPv6 (128-bit, format xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx) addresses are fully supported.
How to Use
- Enter an IPv4 address (e.g., 8.8.8.8), IPv6 address, or fully qualified domain name in the search input field
- Click the Lookup button or press Enter to initiate the query against multiple IP information databases
- Review the geolocation section showing the estimated country, region, city, postal code, and map coordinates for the IP address
- Check the network information panel displaying the Internet Service Provider, organization name, autonomous system number, and connection type
- Use the security and threat detection section to identify whether the IP is flagged as a VPN, proxy, Tor node, or known malicious source
Examples
Input: IP: 8.8.8.8
Process: Query GeoIP database → Map to ASN → Resolve organization
Result: Google LLC, Mountain View US, ASN 15169
Input: IP: 114.114.114.114
Process: Reverse lookup → ISP identification → Region mapping
Result: 114 DNS, China Telecom, Nanjing CN

Frequently Asked Questions
How accurate is IP-based geolocation and what are its limitations?
IP-based geolocation accuracy varies significantly by level: country-level accuracy is generally around 95-98%, region/state level is approximately 80-90%, and city-level accuracy ranges from 50-80% depending on the database and location. The accuracy is limited because IP geolocation databases map IP address blocks to locations based on registration records and network routing data, not GPS coordinates. Large ISPs may register their IP blocks at corporate headquarters while customers are distributed nationally or globally. Mobile carrier IPs often appear at the carrier's core network location rather than the user's actual position. VPN and proxy services will show the server location rather than the user's real location, which is an intentional feature for privacy but a limitation for geolocation accuracy.
What is the difference between a static IP and a dynamic IP address?
A static IP address is permanently assigned to a device or network and never changes. Static IPs are used for servers, network equipment, remote access systems, and services that need consistent addressing. The advantages include reliable DNS resolution, easier remote access setup, and stable geolocation mapping. A dynamic IP address is temporarily assigned from a pool of available addresses by the ISP's DHCP server, typically changing every few days, weeks, or whenever the modem reconnects. Dynamic IPs are standard for residential and most business connections because they allow ISPs to reuse address space efficiently. Dynamic IPs make geolocation less consistent over time and can cause issues for services that rely on IP-based identification.
Can I look up my own public IP address with this tool?
Yes, simply leave the input field empty and click Lookup, or type myip as the query term. The tool will automatically detect and display your current public IP address along with all associated geolocation and network information. This is particularly useful if you need to whitelist your IP in a firewall rule, verify that your VPN is working correctly (your displayed IP should be different from your actual one when VPN is active), or check the location that websites and services see when you connect. Note that the IP shown is your public-facing address as seen by external servers, which may differ from your local private IP (192.168.x.x or 10.x.x.x) assigned by your router.
What information can be learned about an IP address and what are the privacy implications?
The tool provides geolocation (country, city, coordinates), network ownership (ISP, organization), connection type (residential, business, mobile, datacenter), security flags (VPN, proxy, Tor, abuse history), and timezone data. Privacy-wise, this reveals approximate location of the user behind the IP but not their exact street address, name, or personal identifying information. However, combined with other data points, IP information can contribute to user profiling. GDPR and other privacy regulations consider IP addresses as personal data in many jurisdictions. If you are a regular internet user concerned about privacy, using a reputable VPN service will show the VPN provider's IP and location instead of your own when any lookup tool is used to query your address.
Why does my IP geolocation show the wrong city or region?
IP geolocation showing an incorrect or distant city is a common occurrence with several typical causes. Your ISP may allocate IP addresses from a centralized pool registered at their headquarters location rather than your local area, particularly common with smaller regional ISPs that obtain IP blocks from larger carriers. For mobile connections, carrier-grade NAT (CGNAT) means many users share the same public IP address registered at the carrier's core network facility, often in a different city or region. Corporate networks may route all traffic through a central office or data center in another state or country. Database lag is another factor: when IP blocks are transferred between ISPs, geolocation databases may not update for weeks to months.
