about city data

[zuozhehao]

Is there a specific document on the data structure and examples related to city

[horgh]

We currently don't have documentation about the structure of the MMDBs. Typically it is easiest to use one of our API clients.

However, one way you can look at the structure is by using https://github.com/maxmind/mmdbinspect or mmdblookup from https://github.com/maxmind/libmaxminddb for an IP/network. Note that not every IP/network has every value populated though.
