How it works

Understand the network behind an address

The endpoint enriches an IP address with hostname, ASN, network ownership, user and connection type, location, timezone, and anycast information. It does not make an allow or block decision for you.

IP location and network metadata represent the information available for the queried address. They should not be treated as a precise physical location for an individual person.

Integration examples

Replace the sample IP with the address you need to enrich and allow for fields that are unavailable for a particular network. Read the complete IP Lookup documentation.
