Alibaba.com LLC AL-3 (NET-47-235-0-0-1) 47.235.0.0 - 47.246.255.255
另外建议除了 CIDR 版以外,还可以提供 IP Range 版:现在从 https://ispip.clang.cn/ 下载的文件,不管是否带有 _cidr 后缀,貌似其实都是 cidr 格式的。比如:https://ispip.clang.cn/chinatelecom.txt 其实与 https://ispip.clang.cn/chinatelecom_cidr.txt 一样,都是 CIDR 格式?
希望有类似 APNIC Whois 返回的这种“47.235.0.0 - 47.246.255.255” IP Range 格式的版本。IP Range 版本有助于降低索引条目数,提升搜索效率。
例如:将上述单条 IP Range 47.235.0.0 - 47.246.255.255 转换为 CIDR 表述,会生成如下 5 条记录:
47.235.0.0 - 47.246.255.255
47.235.0.0/16 47.236.0.0/14 47.240.0.0/14 47.244.0.0/15 47.246.0.0/16
条目数变多显然会导致搜索和匹配效率下降(例如:B树索引的搜索效率为 O(log(N)),显然 N 越小性能越好)。因此希望能够生成 IP rnage 版本。
