IP Lookup

Check details for any IP address.

What This Tool Does

Our IP lookup tool queries multiple geolocation databases to provide comprehensive information about any IP address. Simply enter an IP address to discover its approximate geographic location, the Internet Service Provider (ISP) that owns it, the Autonomous System Number (ASN), and other network details. This works for both IPv4 and IPv6 addresses.

Common Use Cases

Verify the location of a suspicious IP accessing your server
Check which ISP and network block owns an IP range
Investigate the origin of spam or malicious traffic
Confirm your own public IP address and location data
Debug geolocation issues in web applications

Frequently Asked Questions

How accurate is IP geolocation?

IP geolocation is typically accurate at the country and city level (80-95% accuracy), but cannot pinpoint exact street addresses. Mobile IPs and VPNs may show incorrect locations. ISP and ASN data is highly accurate as it comes from official registry records.

Can I look up any IP address?

Yes, you can look up any valid public IPv4 or IPv6 address. Private IP addresses (like 192.168.x.x or 10.x.x.x) cannot be geolocated as they are not routable on the internet.

What is an ASN (Autonomous System Number)?

An ASN is a unique identifier assigned to networks (like ISPs or large organizations) that participate in internet routing. It helps identify who manages a particular IP address block.
