从pingable IP地址中获取MAC地址列表

Question

目标:获取一个数组，其中包含主机名(通过DNS，如果没有找到，则为空)、网络上活动设备的MAC地址和IP地址。这必须适用于非窗口设备(交换机、ESX主机等)，这样WMI就失效了。

我到目前为止所拥有的，基于这个帖子

Param (
    [string]$Network = "192.168.1",
    [int]$IPStart = 1,
    [int]$IPEnd = 255
)

$outArray = @()
ForEach ($IP in ($IPStart..$IPEnd))
{
    Try {
        $Ping = Get-WMIObject Win32_PingStatus -Filter "Address = '$Network.$IP' AND ResolveAddressNames = TRUE" -ErrorAction Stop
    }
    Catch {
        $windows = 0
        $hostname = ([system.net.dns]::GetHostByAddress($IP)).hostname
        Continue
    }
    if ($Ping.StatusCode -eq 0)
    {
        Try {
            $Adapters = Get-WmiObject Win32_NetworkAdapter -Filter "NetEnabled = True" -ComputerName $Ping.ProtocolAddressResolved -ErrorAction Stop
        }
        Catch {
            $windows = 0
            Continue
        }
        if ($windows -ne 0) {

有几种方法可以从Windows计算机远程获取MAC地址。

getmac /S <computername> /FO CSV | ConvertFrom-Csv

或

Get-WmiObject win32_networkadapterconfiguration | select description, macaddress

我发现getmac通常是您想要的数据，WMI查询需要进行一些过滤。但是，您可以根据您在脚本中发现的网络接口来比较和筛选来自WMI查询的结果。

另外，将[int]$IPEnd = 255更改为[int]$IPEnd = 254 255是网络的广播地址。

编辑：好吧，因为您似乎有一组要求很高的约束，但是您有一个冲突域(很高兴听到这个消息！)

似乎您需要直接调用iphlpapi.dll。

有人已经解开了这个谜团，但是看看这个脚本：http://poshcode.org/2763
