用APNIC找出台灣所有的IP位址

台灣的IP網段

台灣的IP地址是由APNIC(亞太網路資訊中心)分配，所以在APNIC官網上就可以查詢到最新分配给亞洲各國網段資料（當然包含台灣囉）。

連接以下的網址 http://ftp.apnic.net/apnic/stats/apnic/delegated-apnic-latest， 網友們就可以得到亞太地區的AS號和網段分配情况，如下：

檔案格式的說明如下：

配發的機構 | 國家代碼｜IP版本| 分配網段 | 分配IP數量 | 分配時間 | 狀態

apnic|TW|asn|1659|1|20020801|allocated

因此，若要取得該國的網段，這還需要再做進一步的IP Mask計算處理：

wget -O- 'http://ftp.apnic.net/apnic/stats/apnic/delegated-apnic-latest' | awk -F\| '/TW\|ipv4/ { printf("%s/%d\n", $4, 32-log($5)/log(2)) }' > ./tw_ip.list

這樣就會取得所有台灣的IP網段~~ ：） 但是有網友需要所有的IP位址，這下就要花點小技巧囉： 首先請到 Github上面安裝 ipgen 這個專案項目 1.安装ipgen $ git clone https://github.com/royhills/ipgen.git $ cd ipgen $ autoreconf --install $ ./configure $ make $ make check $ sudo make install   注意事前必須先安装 automake 和 autoconf 套件   2. IP Generation Script #!/bin/bash while read line do         ipgen $line | tee -a ./tw.ip_address.list done < ./tw_ip.list 所以全台灣的IP檔案大小約 489MB， 35,510,560 個IP(約3千多萬組IP) <那.....中國有多少？？> 是的~~ 中國的IP檔案大小約 4.6GB， 338,261,890 個IP(約3億3千多萬組IP)
