IPinfo Core API Developer Resource

The IPinfo Core API is our entry-level premium API access plan, which includes granular geolocation information, ASN information, network flags, and access to the dedicated ASN API.

Geolocation information: City, Region/State, Country, Postal code etc.
ASN information: ASN (Autonomous System Number), AS Name, ASN Domain and ASN Type
Network flags: Anonymous IP address (VPN, proxy, Tor, or relay), Hosting IP address (data center or server IP), Anycast IP, Carrier mobile IP flag, and Satellite IP address

You can access IPinfo Core data as a downloadable dataset as well: IPinfo Core IP Data Downloads

The IPinfo Core also supports ASN lookups via the ASN API:

curl https://ipinfo.io/AS18952?token=$TOKEN

{
  "asn": "AS18952",
  "name": "Big Valley of Pomo Indians of the Big Valley Rancheria California",
  "country": "US",
  "allocated": "2017-08-30",
  "registry": "arin",
  "domain": "big-valley.net",
  "num_ips": 512,
  "type": "government",
  "prefixes": [
    {
      "netblock": "162.208.96.0/24",
      "id": "BVR-NETS",
      "name": "Big Valley of Pomo Indians of the Big Valley Rancheria California",
      "country": "US",
      "size": "256",
      "status": "ALLOCATION",
      "domain": "big-valley.net"
    },
    {

    }
  ],
  "prefixes6": [],
  "peers": ["7018"],
  "upstreams": ["7018"],
  "downstreams": null
}

The API endpoint also supports explicit declaration of IP address connections (IPv4/IPv6).

Description	Endpoint type	Endpoint
General (Dual Stacked)	Self / Client IP	`curl https://api.ipinfo.io/lookup/me?token=$TOKEN`
General (Dual Stacked)	Lookup / Target IP	`curl https://api.ipinfo.io/lookup/8.8.8.8?token=$TOKEN`
IPv4	Self / Client IP	`curl https://v4.api.ipinfo.io/lookup/me?token=$TOKEN`
IPv4	Lookup / Target IP	`curl https://v4.api.ipinfo.io/lookup/8.8.8.8?token=$TOKEN`
IPv6	Self / Client IP	`curl https://v6.api.ipinfo.io/lookup/me?token=$TOKEN`
IPv6	Lookup / Target IP	`curl https://v6.api.ipinfo.io/lookup/8.8.8.8?token=$TOKEN`

The general API endpoint is built to support both IPv4 and IPv6 connection, ensuring you can call it from either without any issues.

Alternative API Schema

Our legacy API is still maintained with fresh data, and we are committed to providing continued service to existing customers.

IPinfo Core (Legacy)

Built on top of the IPinfo Basic tier API service, the IPinfo Core API service includes the IPinfo Core API and the network flags.

curl  https://ipinfo.io/8.8.8.8/json?token=$TOKEN

{
  "ip": "8.8.8.8",
  "hostname": "dns.google",
  "city": "Mountain View",
  "region": "California",
  "country": "US",
  "loc": "37.4056,-122.0775",
  "postal": "94043",
  "timezone": "America/Los_Angeles",
  "is_anycast": true,
  "is_mobile": false,
  "is_anonymous": false,
  "is_satellite": false,
  "is_hosting": true,
  "asn": {
    "asn": "AS15169",
    "name": "Google LLC",
    "domain": "google.com",
    "route": "8.8.8.0/24",
    "type": "hosting"
  }
}

IPinfo Basic (Legacy)

IPinfo Basic has been upgraded to the IPinfo Core API tier. It now includes network flags and extended geolocation details that were previously not available in the Basic tier.
