为什么 Maxmind 的 GeoLite2 City 数据库 return 不存在 geoname_id？
Why does Maxmind's GeoLite2 City database return non-existent geoname_id?
我已经下载了 Maxmind 的 GeoLite2 City 数据库的最新更新（MaxMind DB 二进制和 CSV 格式）。当我试图查找“88.184.98.0”时，我得到的是：
{"city":{"geoname_id":2982652,"names":{"de":"Rouen","en":"Rouen","es":"Ruan","fr":"Rouen","ja":"ルーアン","pt-BR":"Ruão","ru":"Руан","zh-CN":"鲁昂"}},"continent":{"code":"EU","geoname_id":6255148,"names":{"de":"Europa","en":"Europe","es":"Europa","fr":"Europe","ja":"ヨーロッパ","pt-BR":"Europa","ru":"Европа","zh-CN":"欧洲"}},"country":{"geoname_id":3017382,"is_in_european_union":true,"iso_code":"FR","names":{"de":"Frankreich","en":"France","es":"Francia","fr":"France","ja":"フランス共和国","pt-BR":"França","ru":"Франция","zh-CN":"法国"}},"location":{"accuracy_radius":5,"latitude":49.4431,"longitude":1.0993,"time_zone":"Europe/Paris"},"postal":{"code":"76100"},"registered_country":{"geoname_id":3017382,"is_in_european_union":true,"iso_code":"FR","names":{"de":"Frankreich","en":"France","es":"Francia","fr":"France","ja":"フランス共和国","pt-BR":"França","ru":"Франция","zh-CN":"法国"}},"subdivisions":[{"geoname_id":11071621,"iso_code":"NOR","names":{"de":"Normandie","en":"Normandy","es":"Normandía","fr":"Normandie"}},{"geoname_id":2975248,"iso_code":"76","names":{"de":"Seine-Maritime","en":"Seine-Maritime","es":"Sena Marítimo","fr":"Seine-Maritime","pt-BR":"Sena Marítimo"}}]}
但是，CSV 文件中返回的细分没有相应的 geoname_id（例如 cat GeoLite2-City-Locations-en.csv | grep 11071621 returns 没有）。
这是错误还是预期行为？我在文档中找不到任何内容。
我已寻求支持，答案是这是设计使然。如果没有直接关联的 IP，则 CSV 文件不包含位置。
