Script: To be saved as ps1 script and execute it and create temp directory to save the file.

$vcenter = Read-Host "vCenter"
$cred = Get-Credential

Connect-VIServer $vcenter -Credential $cred

$result = Get-VMHost | ForEach-Object {

    $h = $_
    $esxcli = Get-EsxCli -VMHost $h -V2

    try {
        $bmc = $esxcli.hardware.ipmi.bmc.get.Invoke()

        # Extract IPv4 only
        $ipv4 = $bmc.IPv4Address

        [PSCustomObject]@{
            Host        = $h.Name
            IPv4Address = $ipv4
        }
    }
    catch {
        [PSCustomObject]@{
            Host        = $h.Name
            IPv4Address = "Not Available"
        }
    }
}

# Export to CSV
$csvPath = "C:\Temp\ESXi_BMC_IPs.csv"
$result | Export-Csv -Path $csvPath -NoTypeInformation

# Optional: also display nicely in console
$result | Format-Table -AutoSize

Write-Host "Report saved to $csvPath"
