显示NIC信息

Question

在下面的代码中，$ipAddress同时存储IPV4和IPV6。我只想要显示IPV4，有没有办法做到这一点？也许可以用分叉？

此外，子网掩码还会打印255.255.255.0 64 -这个恶意64是从哪里来的？

代码：

ForEach($NIC in $env:computername) {
    $intIndex = 1
    $NICInfo = Get-WmiObject -ComputerName $env:computername Win32_NetworkAdapterConfiguration | Where-Object {$_.IPAddress -ne $null}
    $caption = $NICInfo.Description 
    $ipAddress = $NICInfo.IPAddress
    $ipSubnet = $NICInfo.IpSubnet 
    $ipGateWay = $NICInfo.DefaultIPGateway 
    $macAddress = $NICInfo.MACAddress 
    Write-Host "Interface Name: $caption"
    Write-Host "IP Addresses: $ipAddress" 
    Write-Host "Subnet Mask: $ipSubnet"
    Write-Host "Default Gateway: $ipGateway"
    Write-Host "MAC: $macAddress"
    $intIndex += 1
}

对于IPv6，子网的工作方式不同，所以您看到的流氓64是IPV6的子网掩码，而不是IPV4的子网掩码。

IPv6中的前缀长度相当于IPv4中的子网掩码。但是，它不像在IPv4中那样以4个二进制八位数表示，而是表示为1-128之间的整数。例如: 2001:db8:abcd:0012::0/64

为了删除它，你可以尝试下面的方法(大量的假设认为IPv4总是排在第一位，但在我所有的实验中，它还没有排在第二位；)

ForEach($NIC in $env:computername) {
    $intIndex = 1
    $NICInfo = Get-WmiObject -ComputerName $env:computername Win32_NetworkAdapterConfiguration | Where-Object {$_.IPAddress -ne $null}
    $caption = $NICInfo.Description
    #Only interested in the first IP Address - the IPv4 Address
    $ipAddress = $NICInfo.IPAddress[0]
    #Only interested in the first IP Subnet - the IPv4 Subnet    
    $ipSubnet = $NICInfo.IpSubnet[0] 
    $ipGateWay = $NICInfo.DefaultIPGateway 
    $macAddress = $NICInfo.MACAddress 
    Write-Host "Interface Name: $caption"
    Write-Host "IP Addresses: $ipAddress" 
    Write-Host "Subnet Mask: $ipSubnet"
    Write-Host "Default Gateway: $ipGateway"
    Write-Host "MAC: $macAddress"
    $intIndex += 1
}

希望这能有所帮助！
