简介

本脚本是上一篇博文的功能拓展，主要功能

1. 解析域名ip
2. 分别ping所解析到的ip
3. 自定义ping次数

部分代码原理

仅使用 DNS 解析名称。 不会发出 LLMNR 和 NetBIOS 查询。

Resolve-DnsName -Name pdc.chana.com -DnsOnly

匹配ping返回的结果$pingPDCTextBox.Text为可自定义ping次数

ping $ipArray[$i] -n $pingPDCTextBox.Text | Where-Object {$_ -match "回复" -or $_ -match "Reply" -or $_ -match "请求超时" -or $_ -match "Request timed out" -or $_ -match "无法访问目标主机" -or $_ -match "Destination host unreachable"}
