[Feature Request] Support IPinfo MMDB databases

[abdullahdevrel]

Hi PostHog team,

I am the DevRel of IPinfo, an IP data company. I have some experience with Posthog and tried to implement the feature myself, but I think the scale is just too big.

We have users who have reached out to us about using IPinfo MMDB databases in an analytics platform. The problem is that we do not have any off-the-shelf solutions to support this request. We would like to request that Posthog support the MMDB reader functionality and data update mechanism as a solution for IPinfo.

Our database is in MMDB format and is tabular in nature. While the existing provider's data is unpredictable and nested in nature, our data is tabular with a clear structure. We return an empty string when a value is not present. The MMDB reader library will work perfectly with our data. Additionally, our data can be updated via the storage URI, which accepts the access token as a parameter.

Users requested database support for:

• IP to Country ASN database (Free)
• IP to Geolocation database
• IP to Privacy Detection Database

If you can cover only one database, we can reuse the code to write for the rest of our databases.

The documentation of the IP databases is available here:

• https://ipinfo.io/developers/database-types
• https://ipinfo.io/developers/database-download
• https://ipinfo.io/developers/database-filename-reference

You can find the sample MMDB databases here: https://github.com/ipinfo/sample-database

Please let me know what you think. Thank you.
