配置智能DNS時獲取各運營商IP段




原文請訪問：http://m114.org
APNIC是管理亞太地區IP地址分配的機構，它有著豐富準確的IP地址分配庫，同時這些信息也是對外公開的！

在Linux下獲得一些國內運營商的IP地址段的情況：



1、編譯安裝軟體shell> wget http://ftp.apnic.net/apnic/dbase/tools/ripe-dbase-client-v3.tar.gz

•shell> tar xzvf ripe-dbase-client-v3.tar.gz

•shell> cd whois-3.1

•shell> ./configure

•shell> make && make install複製代碼
2、獲取IP並轉換為智能DNS格式#!/bin/bash
