运行环境:Windows Server 2012 R2
获取服务器DNS命令,下面的仅获取一个dns
(nslookup sql.ciras.com)[1].split(‘:‘)[1].trim()
此脚本用来验证DNS是否正常,实际原理就是ping域名的ip
先ping域名
再解析域名的ip地址
判断域名是否解析域名是否为多个ip
若为多个ip,则再次ping文件中给的ip地址
最后输出表格

附带的txt文件格式
输入格式【域名,IP】(中间使用英文逗号分隔),请保留本行且不能包含空行。 www.baidu.com,127.0.0.1 www.baidu.com,127.0.0.2 www.baidu.com,127.0.0.3 www.baidu.com,127.0.0.4
