Contradiction between GeoLite2 database and GeoIP2

问题:

I am using the GeoLite2 city-blocks and city-location free databases and found the following ip_addresses have same locid number of 223, however if I type these addresses to GeoIP2 precision web service it gives me 4 different location information. Should one locid number correspond to only one location? I am really confused?

12.234.227.170 (WI, US by GeoIP2) 69.174.58.60 (IL, US by GeoIP2) 71.216.182.245 (Bremerton, Washington by GeoIP2) 74.44.255.2 (Lakeville MN by GeoIP2)

GeoLite2 and GeoIP2 Precision results will differ in many cases. GeoLite2 provides access to free, less accurate data than is available in the GeoIP2 Precision Web Services. (Note: I work for MaxMind, the company that creates GeoLite2 and GeoIP2 products.)
