I compared IPinfo’s answers to MaxMind’s https://www.maxmind.com/en/geoip-demo
answers,
for a random recent visitor from 44.198.66.156 to my website
https://cryptosystemsjournal.com/
and one notable difference is that you specify a larger CIDR block of
44.192.0.0/11 (2,097,152 addresses)
whereas MaxMind specifies a much smaller CIDR block 44.198.64.0/19 (8,192
addresses).

Unfortunately, there is not a quality academic paper that has come out
yearly comparing the various geo-location DBs and their accuracy (IPv4 &
IPv6) down to the 100m-1km level. So in the interim, we will continue
to see geo-location DB wars - just like we have had OS wars and IP vs
OSI wars.
