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. Regards, Hank
