Free IP Lookup Tool — Find IP Geolocation, ISP & Network Details Instantly

What Is an IP Lookup?

An IP lookup (also called IP geolocation lookup) is the process of determining the approximate geographic location, ISP, organization, and network details associated with an IP address. Every device connected to the internet has a unique IP address — and our free tool lets you instantly retrieve detailed information about any IPv4 or IPv6 address.

Whether you're investigating suspicious traffic, verifying a VPN connection, or researching a competitor's hosting infrastructure, our IP lookup tool delivers accurate results in seconds.

Why IP Lookups Matter

Understanding IP addresses is critical for network security, website analytics, and digital marketing. IP lookups help you:

• Identify visitor locations — Understand where your website traffic comes from geographically
• Detect fraud — Flag suspicious login attempts from unexpected locations
• Verify hosting — Confirm which data center and provider hosts a website
• Troubleshoot network issues — Trace connectivity problems to specific networks
• Comply with regulations — Geo-restrict content based on visitor location (GDPR, licensing)

What Information Does an IP Lookup Reveal?

Geographic Location

An IP lookup reveals the approximate location of the IP address — typically the city, region, and country. Note that IP geolocation is not precise enough to identify a street address; it estimates location based on ISP records.

ISP & Organization

Discover which Internet Service Provider owns the IP block and the organization it's assigned to. This is useful for identifying whether traffic comes from residential users, data centers, or corporate networks.

Network Details

View the ASN (Autonomous System Number), IP range, and routing information associated with the address. Technical teams use this for network analysis and peering decisions.

Connection Type

Determine whether an IP belongs to a residential, business, hosting/data center, or mobile connection — helpful for fraud detection and ad targeting.

How to Use Our IP Lookup Tool

1. Enter any IPv4 or IPv6 address in the input field
2. Click the lookup button
3. Review the detailed results — location, ISP, organization, and more
4. Use the information for troubleshooting, research, or security analysis

Common Use Cases

• Website analytics — Map visitor IP addresses to geographic regions
• Cybersecurity — Investigate the origin of attacks, spam, or suspicious logins
• Email header analysis — Trace the source IP of an email to verify authenticity
• VPN verification — Confirm your VPN is masking your real location
• Content delivery — Optimize CDN settings based on user geography

IP Lookup Best Practices

• Remember that IP geolocation is approximate — it won't pinpoint an exact street address
• VPNs, proxies, and Tor can mask the true origin of an IP address
• Cross-reference IP data with other tools (DNS, Whois) for comprehensive analysis
• Use IP lookups alongside analytics to identify bot traffic from data center IPs
• Check both IPv4 and IPv6 addresses for complete network visibility

Frequently Asked Questions

How accurate is IP geolocation?

IP geolocation is typically accurate to the city level for most residential connections. Accuracy varies — it's usually 80-95% accurate at the country level and 50-80% at the city level. VPNs and proxies can make results unreliable.

Can I find someone's exact address with an IP lookup?

No. IP lookups only provide approximate geographic information — usually the city or region. Only the ISP can link an IP to a specific subscriber, and they require a legal order to disclose that information.

What's the difference between IPv4 and IPv6?

IPv4 addresses use a 32-bit format (e.g., 192.168.1.1) with about 4.3 billion possible addresses. IPv6 uses 128 bits (e.g., 2001:db8::1) and supports virtually unlimited addresses to accommodate the growing internet.

Why does my IP show a different city than where I am?

Your ISP may route your connection through a hub in a nearby city. If you're using a VPN or proxy, the lookup will show the VPN server's location instead of yours.
