What Is an IP Lookup?

An IP address lookup (also called IP geolocation or IP WHOIS) is the process of finding information associated with an IP address. This includes the country, region, and city where the IP is registered; the ISP or organization that owns the IP block; the Autonomous System Number (ASN); and metadata like whether the IP belongs to a proxy, VPN, hosting provider, or mobile network.

What Is an ASN?

An Autonomous System Number (ASN) is a unique identifier assigned to a network that connects to the internet. ISPs, cloud providers, universities, and large corporations each have their own ASN. ASNs are used for internet routing — routers use them to decide how to forward packets across the global internet. Knowing the ASN of an IP tells you exactly which network (and therefore which organization) owns it.

Frequently Asked Questions

What information can I get from an IP address?›
An IP lookup returns the approximate country, region, and city; the ISP or organization that owns the IP block; the Autonomous System Number (ASN); timezone; and flags for proxy, VPN, hosting, or mobile network classification.
How accurate is IP geolocation?›
Country-level accuracy is typically 99%+. Region (state/province) accuracy is around 80–90%. City-level accuracy varies widely — it may be off by dozens to hundreds of kilometers, especially for mobile or satellite IPs.
Can I look up a domain name instead of an IP?›
Yes. Enter a domain like "google.com" and the tool will resolve it to an IP first, then return the geolocation data for that IP.
What does the proxy flag mean?›
The proxy/VPN flag indicates the IP is registered to or used by a known proxy service, VPN provider, or Tor exit node. Sites use this flag to decide whether to block or challenge requests.
Why does an IP show a different location than expected?›
IP-to-location mapping is based on registration data — where the IP block was allocated — not the physical location of the device using it. Corporate VPNs, CDNs, and ISPs that reassign IP blocks frequently cause location mismatches.
