关于APNIC

    全球IP地址块被IANA(Internet Assigned Numbers Authority)分配给全球三大地区性IP地址分配机构,它们分别是:

ARIN (American Registry for Internet Numbers)

    负责北美、南美、加勒比以及非洲撒哈啦部分的IP地址分配。同时还要给全球NSP(Network Service Providers)分配地址。

RIPE (Reseaux IP Europeens)

    负责欧洲、中东、北非、西亚部分地区(前苏联)

APNIC (Asia Pacific Network Information Center)

    负责亚洲、太平洋地区

APNIC IP地址分配信息总表的获取:

APNIC提供了每日更新的亚太地区IPv4,IPv6,AS号分配的信息表:http://ftp.apnic.net/apnic/stats/apnic/delegated-apnic-latest
该文件的格式与具体内容参见:ftp://ftp.apnic.net/pub/apnic/stats/apnic/README.TXT

通过该文件我们能够得到APNIC辖下IPv4地址空间的分配情况。

脚本获取IP地址

#!/bin/bash
wget -c http://ftp.apnic.net/stats/apnic/delegated-apnic-latest

cat delegated-apnic-latest | awk -F '|' '/CN/&&/ipv4/ {print $4 "/" 32-log($5)/log(2)}' | cat > ipv4.txt

cat delegated-apnic-latest | awk -F '|' '/CN/&&/ipv6/ {print $4 "/" 32-log($5)/log(2)}' | cat > ipv6.txt

cat delegated-apnic-latest | awk -F '|' '/HK/&&/ipv4/ {print $4 "/" 32-log($5)/log(2)}' | cat > ipv4-hk.txt

cat delegated-apnic-latest | awk -F '|' '/HK/&&/ipv6/ {print $4 "/" 32-log($5)/log(2)}' | cat > ipv6-hk.txt

执行脚本:

[root@cby cby]# ./ip.sh

每日凌晨十二点十分会进行同步,若需要IP地址,可以访问如下地址:
