Interesting project.
Noticed that your project utilized two libs by oschwald, it not only supported MaxMind's mmdb but dp-ip's.
go: downloading github.com/oschwald/maxminddb-golang v1.9.0 go: downloading github.com/oschwald/geoip2-golang v1.7.0
therefore, I had a try to convert mmdb format to CSV on ip-to-city-lite
Originally, mmdb file size was 92.0 MB, csv file size was 447.8 MB
.
Converted mmdb to csv. the file size bump up to 2.92 GB (3,143,647,192 bytes)
what happened?
BTW, MaxMind provided mmdb and csv format both for ASN, Country, and City, what reasons drove you to make this project?
