IP Lookup
Look up location, network, and ASN details for any public IPv4 or IPv6 address.
What This Tool Does
Our IP lookup tool checks a public IP address and returns approximate location, ISP, ASN, and related network context. It works with both IPv4 and IPv6 addresses and is useful for quick diagnostics, verification, and investigation.
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.
