Powershell 如何为测试连接设置变量以获取IPV4地址？

我为这个糟糕的标题道歉，我不知道该怎么说

我想设置一个脚本，当运行时，它会执行一个if-then命令，输出计算机名、连接是否失败或成功以及连接后的IP是什么

到目前为止，我得到的是：

    $computer1 = 'google.com'
    $computer2 = 'netflix.com'
if (Test-Connection "$computer1" -count 1 -Quiet) {"$computer1 connected"} else {"$computer1 failed"}
if (Test-Connection "$computer2" -Count 1 -Quiet) {"$computer2 connected"} else {"$computer2 failed"}

因此，产出：

Google.com已连接

Netflix.com失败了

我怎样才能更进一步，当它返回时，它会说：

Google.com已连接“IPv4address”

其中显示IPv4地址、已连接地址和计算机名称

就像您最初测试连接时的方式一样：

test-connection google.com

这就返回了：

Source        Destination     IPV4Address

------        -----------     -----------    
DOMINATOR     google.com      172.217.9.206
DOMINATOR     google.com      172.217.9.206
DOMINATOR     google.com      172.217.9.206
DOMINATOR     google.com      172.217.9.206

我之所以这么问是因为当一个连接失败时，它会抛出一个恼人的消息：

PS C:\Users\Andrew> Test-Connection netflix.com, google.com

当然你可以加上“安静”

但它只是说：

False
True

任何帮助都将是巨大的，因为我被难住了

这里有一种优雅地处理失败的方法

$targets = 'server1', 'server2', 'server3', 'dontexist'

$success = Test-Connection -ComputerName $targets -Count 1 -ErrorAction SilentlyContinue -ErrorVariable errors |
               Select-Object @{n='Server';e={$_.address}},IPv4Address,@{n='Result';e={'Successful'}}

$failed = $errors.exception.message |
              Where-Object {$_ -match "computer '(.+?)'"} |
                  Select-Object @{n='Server';e={$matches.1}},
                                @{n='IPv4Address';e={"N/A"}},
                                @{n='Result';e={'Failed'}}

$success + $failed

看看我的答案，这正是我需要的。非常感谢你。
