Question

在以下代码中，$ ipAddress存储IPV4和IPV6。我只想要显示IPV4，无论如何这可以做到吗？也许是分裂？

此外，子网掩码打印255.255.255.0 64 - 这个流氓64来自哪里？

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
}

子网对IPv6的工作方式不同，因此您看到的流氓64是IPv6的子网掩码 - 而不是IPv4。

IPv6中的prefix-length相当于IPv4中的子网掩码。但是，不是像在IPv4中那样以4个八位字节表示，而是表示为1-128之间的整数。例如：2001：db8：abcd：0012 :: 0/64

见这里：http://publib.boulder.ibm.com/infocenter/ts3500tl/v1r0/index.jsp?topic=%2Fcom.ibm.storage.ts3500.doc%2Fopg_3584_IPv4_IPv6_prefix_subnet_mask.html

为了删除它，您可以尝试以下方法（大量假设IPv4始终排在第一位，但在我的所有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
}

希望这有帮助！
