# Research IP Address Ownership

When you encounter an unfamiliar IP address -- in server logs, email headers, or security alerts -- the first question is always "who owns this?" IP geolocation answers that by returning the ISP, organization, and network details behind any IP address.

The lookup skill provides the autonomous system number (ASN), ISP name, organization, and geographic location for any IP. This is faster and more accessible than raw WHOIS queries, and the results are structured for immediate analysis.

Security researchers use this to trace attack origins. Sales teams use it to identify which companies are visiting their website. IT teams use it to verify that third-party services are operating from expected networks. The ownership data transforms an opaque number into an actionable identity.
