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!

Any feedback please shoot me an email: ben@ipinfo.io

We've just launched an opensource golang `ipinfo` cli that lets you quickly and easily get IP address data from the cli. You can lookup geolocation, isp, carrier & vpn status for a single IP (in much the same way you can by `curl ipinfo.io`) but there's a bunch of additional functionality, including:

- bulk lookups of IPs - summarize IPs (so get top ASNs, cities etc from a ton of IPs) - grepip subcommand to grep for IPs (v4, v6 and bogon flags available) - map command to map a bunch of IPs

And more! See https://github.com/ipinfo/cli for more details and installation instructions

We recently launched a free tool that shows a summary of the top cities, countries, asns, routes and much of the other context that we (IPinfo) have for any IP addresses you paste into it.

Sample results: https://ipinfo.io/summarize-ips/result?id=239e90aa-88b8-4476-84c7-bfd10ed2de3f

You can paste any arbitrary text into the tool at https://ipinfo.io/summarize-ips and we'll extract the IPs.

It can be useful for getting a quick summary of a set of IPs (eg. click on first google result for "public proxies", copy and paste the results into the tool, and see where the proxies are located, and the networks they're on), for investigating issues (eg. your website gets a large spike of traffic, paste the recent IPs from your access log into the tool and see if there's a specific network that stands out), threat investigation, debugging and more.

We're planning to add more functionality and data points in the near future, and any feedback or suggestions are very welcome!
