You can use IPinfo's IP map (https://ipinfo.io/tools/map) or IP summary tool (https://ipinfo.io/tools/summarize-ips).

Both of these services support sending IP addresses via an API endpoint and can handle up to 500k IP addresses. You can also share the report via URL.

Thanks for the tip. I'm also working on a similar analysis where I need to geolocate a bunch of IP addresses at once.

Feel free to check out the IPinfo CLI: https://github.com/ipinfo/cli

I highly recommend the following commands:

  - grepip: extract IP addresses from text.
  - summarize: The command summarizes the IP addresses and provides output in text. It is different than the summary tool I mentioned.
  - bulk: Bulk/batch enrich IP address. Output can be CSV or JSON.

If you need any help or want me to take a look at those IP addresses (or ASNs and organizations), please create a post on the IPinfo community. I can share the code and instructions with you.
