有谁知道这已经打包？此外，有没有对数据进行任何类型的复制保护的？

Does anyone know how this has been packaged? Also, is there any kind of copy protection on the data?

我想提供了一组数据以类似的方式。

I'd like to offer up a set of data in a similar way.

任何对这个一无所知能收到我永远感谢： - ）

Anyone with any knowledge of this will receive my undying gratitude :-)

推荐答案

这只是一个专有的二进制格式，IP地址查询大量优化。它不具有任何拷贝保护

It's just a proprietary binary format, heavily optimized for IP address querying. It doesn't have any copy protection.

如果你真的想反向工程，格式，看看在 C＃或的Java API

If you really want to reverse-engineer the format, take a look at the C# or Java API.
