sinaip

一个使用Sina的IP地址数据库

使用方法

数据已经全部用json格式化好了。 其中 start_ip和end_ip都是以IP2Long形式展现,建议使用二分查找查找范围即可

数据结构

public class sinaip {
    long start_ip;
    long end_ip;
    long point;
    String country;
    String province;
    String city;
    String area;
    String ispType;
    String desc;
    String lat;
    String lnt;
}

Sample.java

public static String searchIP(long ip) {
    int low = 0;
    int high = ip_db.size() - 1;
    while (low <= high) {
        int mid = (low + high) >>> 1;
        sinaip midIP = ip_db.get(mid);
        if (midIP.start_ip < ip && midIP.end_ip < ip) {
            low = mid + 1;
        } else if (midIP.start_ip > ip && midIP.end_ip > ip) {
            high = mid - 1;
        } else {
            return midIP.toString();
        }
    }
    return String.valueOf(-(low + 1));
}
