Powershell获取计算机名,ipv6地址等

```
# 获取计算机名
$computerName = [System.Net.Dns]::GetHostName()

# 获取所有网络接口
$networkInterfaces = Get-NetAdapter | Where-Object { $_.Status -eq "Up" }

# 遍历每个网络接口
foreach ($interface in $networkInterfaces) {
    # 获取全球单播的IPv6地址
    $ipv6Address = Get-NetIPAddress -InterfaceIndex $interface.InterfaceIndex -AddressFamily IPv6 | Where-Object {
        $_.PrefixOrigin -eq "RouterAdvertisement" -and 
        $_.SuffixOrigin -eq "Random" -and 
        ($_.IPAddress -match '^([2400:ff00::/64]|(2001::/32)|(2001:db8::/32)|(2002::/16))') -or 
        ($_.IPAddress -match '^([2000::/3].*)$' -and $_.IPAddress -notmatch '^([fe80::/10]|(fc00::/7))')
    } | Select-Object -First 1 | ForEach-Object { $_.IPAddress }

# 如果存在IPv6地址，则输出计算机名、IPv4地址和IPv6地址
    if ($ipv6Address) {
        # 获取IPv4地址
        $ipv4Address = Get-NetIPAddress -InterfaceIndex $interface.InterfaceIndex -AddressFamily IPv4 | Where-Object { $_.AddressState -eq 'Preferred' } | Select-Object -First 1 | ForEach-Object { $_.IPAddress }

# 输出结果
        $output = "$computerName,$ipv4Address,$ipv6Address"
        Write-Output $output
    }
}
