对于 APNIC
寰球 IP 地址块被 IANA(Internet Assigned Numbers Authority) 调配给寰球三大地区性 IP 地址调配机构，它们别离是：
ARIN (American Registry for Internet Numbers)
负责北美、南美、加勒比以及非洲撒哈啦局部的 IP 地址调配。同时还要给寰球 NSP(Network Service Providers) 调配地址。
RIPE (Reseaux IP Europeens)
负责欧洲、中东、北非、西亚局部地区 (前苏联)
APNIC (Asia Pacific Network Information Center)
负责亚洲、太平洋地区
APNIC IP 地址调配信息总表的获取：
APNIC 提供了每日更新的亚太地区 IPv4，IPv6，AS 号调配的信息表：http://ftp.apnic.net/apnic/stats/apnic/delegated-apnic-latest 该文件的格局与具体内容参见：ftp://ftp.apnic.net/pub/apnic/stats/apnic/README.TXT通过该文件咱们可能失去 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
