获取中国IPV4 IPV6地址CIDR的办法-嘟嘟社区

来源网上
各位大佬看看还有什么改进空间吗？？

curl ‘http://ftp.apnic.net/apnic/stats/apnic/delegated-apnic-latest’ | grep ipv4 | grep CN | awk -F| ‘{ printf("%s/%dn", $4, 32-log($5)/log(2)) }’ > IPV4.txt
curl ‘http://ftp.apnic.net/apnic/stats/apnic/delegated-apnic-latest’ | grep ipv6 | grep CN | awk -F| ‘{ printf("%s/%dn", $4, 32-log($5)/log(2)) }’ > IPV6.txt

复制代码

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

复制代码

1. IP 地址可以广播，APNIC 的更别说；
2. 建议 https://github.com/v2fly/geoip
