I can’t speak for ipinfo, but in comparing free vs commercial data only very basic geolocation by IP is public. This might be due to the IP block allocation (country/region/city) or handy things like ISPs that use geo names in the host name. Many other ranges are opaque blocks or allocated to something like a reseller, etc.

Getting finer grained data down to smaller groups blocks is harder and not public.

Packaging it up into easy to consume (normalized) is yet another layer of work.
