Get answers to common questions about our IP lookup tool
An Internet Service Provider (ISP) is the company that provides you with internet access. Knowing the ISP of an IP address helps identify the source of network traffic, troubleshoot connectivity issues, and understand the origin of website visitors or potential security threats.
An Autonomous System Number (ASN) is a unique identifier assigned to networks for routing purposes on the internet. ASNs help understand how internet traffic flows between different networks and are crucial for network administrators managing routing policies and troubleshooting connectivity issues.
Geolocation accuracy varies depending on the IP address type. For most residential IPs, city-level accuracy is around 85-95%. However, mobile IPs, VPNs, and proxy servers may show less precise locations. Corporate and data center IPs usually provide more accurate results.
No, private IP addresses (like 192.168.x.x, 10.x.x.x, or 172.16-31.x.x) cannot be looked up as they are not routable on the public internet. This tool only works with public IP addresses that are assigned by ISPs and visible on the internet.
No, we prioritize your privacy. We don't log the IP addresses you lookup, store your search history, or use tracking cookies. All lookups are processed in real-time without storing any personal information on our servers.
IPv4 uses 32-bit addresses (like 192.168.1.1) and can provide about 4.3 billion unique addresses. IPv6 uses 128-bit addresses (like 2001:db8::1) and provides virtually unlimited addresses. Both versions are supported by our lookup tool.
Yes, this tool is free for both personal and commercial use. However, if you need high-volume lookups or API access, please contact us for enterprise solutions that can handle larger-scale requirements with guaranteed uptime and support.
Some IP addresses may have limited information available due to privacy settings, recent network changes, or if the IP belongs to a private organization that doesn't publicly share detailed network information. This is normal and doesn't indicate an error with our tool.
