What comes back

Every section below is a key in the response body. Sections we know nothing about are left out rather than returned empty.

location

Geolocation you can audit

Built from RFC 8805 geofeeds the network operators publish themselves, plus registry country and GeoNames reference data. Every result states its semantic precision and whether it came from an operator geofeed or registry allocation.

asn

BGP routing and ASNs

The AS that originates the most specific route covering the address, the announced prefix, and the organization behind the AS number. Query an AS number directly to get every prefix it announces.

network / organization / abuse_contact

Registry whois

The organization holding the allocation, its domain and type, the RDAP link for the network, and the abuse contact the registry publishes — name, email, phone and postal address.

is_datacenter

Datacenter and cloud detection

Published ranges from the major cloud providers, plus hosting networks identified from AS classification. Tells you the provider, its domain and the covering network.

services[]

VPN, proxy and egress

One typed collection covers commercial VPN exits, scanned proxies and platform egress such as iCloud Private Relay, with provider, confidence, exit location and last-seen time.

is_tor / is_abuser

Threat and network flags

Tor exit nodes, blocklisted networks, verified crawlers reported by name, plus mobile, satellite and bogon flags — all as booleans you can branch on directly.

hostname

Reverse DNS

The PTR hostname for the address, resolved ahead of time so the lookup does not wait on DNS.

/api/csv

Four formats and bulk

JSON, CSV, plain text and HTML from the same lookup. POST up to 100 addresses in one request when you need a batch.

One request, no SDK

A plain GET with the address in q. Add your key to get the full body; leave it off for the reduced one.

curl
curl 'https://ip-api.dev/api?q=8.8.8.8&pretty=1&key=YOUR_KEY'

Responses also come as CSV, plain text and HTML from /api/csv, /api/text and /api/html. Full reference →
