I suppose I was overly enthusiastic about the project and overlooked the bulk part . Thank you.
Personally, I prefer to use local MMDB versions as they provide faster results and do not require network usage. Having knowledge about whether an IP is a proxy, VPN, data center, etc. is valuable to me, but I understand that it may vary depending on each project's requirements.
Without wishing to gazump on tuga's excellent project, you can get mmdb files for IPs and ASNs free for personal use from https://ipnetdb.com/ that will probably provide the data you want.
(Disclaimer: I work for the company that develops IPNetDB).
