Free IP to Country and ASN Data downloads:

  - MMDB, CSV and JSON format
  - Full accuracy (not degraded quality compared to our paid downloads)
  - IPv4 and IPv6 data
  - A single file that includes both country and ASN details
  - Daily updated
  - CC Attribution license (no usage restrictions, only requirement is a link back to ipinfo.io)

Here's an example of querying the MMDB file using our mmdbctl tool:

    $ echo "1.1.1.1" | mmdbctl read country_asn.mmdb | jq .
    {
      "as_domain": "cloudflare.com",
      "as_name": "Cloudflare, Inc.",
      "asn": "AS13335",
      "continent": "NA",
      "continent_name": "North America",
      "country": "US",
      "country_name": "United States"
    }

Almost 8 years ago I launched the free IPinfo.io free geolocation API, but until now our data downloads have only been available to our enterprise customers. I'm really happy to be able to offer a subset of our data for free, and excited to see what projects this gets used in!
