IP地址解析DNS

背景

指定IP解析域名，查看解析的域名，常用作CDN地址解析查询是否生效。本文章给出几个解决方案的shell脚本

#方法一： 交互式循环查询操作，exit退出操作，如：./check-ip.sh
#circulate_check

#方法二： 单次查询IP操作，交互式，如：./check-ip.sh
#ip_check

# 方法三： 单次指定IP查询，非交互式，如：./check-ip.sh  120.24.61.213
#ip_auto_check $1

#方法四：  批量处理IP的解析
ip_more_check
#方法五： 菜单式查询，交互式，case语句
#方法六：循环菜单式查询，交互式，while + case语句
