Need to add leading "0" to each octet of IP address

PowerShell Help

I have some code that I have put together but I need to convert each octet to have 3 numbers. If for example I get the IP address of 10.100.33.52 I need to convert it to 010.100.033.052. Here is the code that I have:

Foreach ($UpIp in $Results)
{

$Sqlserver = ‘popsql2k8’
$Sqlcatalog = ‘netops’
$SqlQuery = "SELECT host from dbo.View_DNSxDHCP WHERE dns_ip_alias = ‘$ModIp’"
$Dataset = New-Object System.Data.Dataset
$SqlConnection = New-Object System.Data.SqlClient.SqlConnection
$SqlConnection.ConnectionString = "Server = $SqlServer; Database = $SqlCatalog; Integrated Security = True"
$SqlCmd = New-Object System.Data.SqlClient.SqlCommand
$SqlCmd.CommandText = $SqlQuery
$SqlCmd.Connection = $SqlConnection
$SqlAdapter = New-Object System.Data.SqlClient.SqlDataAdapter
$SqlAdapter.SelectCommand = $SqlCmd
$SqlAdapter.Fill($Dataset)
$Dataset.Tables[0]
$SqlConnection.Close()
[string]$Comp = @($Dataset.Tables[0])[0].host
invoke-command -computername $Comp -filepath c:\Temp\Wol1.ps1
}

$UpIp is a collection of IP’s in a specific subnet and I need to convert them to the format I talked about above to get the $ModIp variable so that I can match them to my DNS table. Thanks!

I’m assuming that $ModIP is the modified IP address that you’re looking for.

$ModIP = ($UpIP.Split('.') | foreach {"0:000}" -f [int]$}) -join '.'

Yes…$ModIp is the modified IP address that I need. With that line of code I get the following errors:

Thanks for your help!

Where did you put it? It needs to go inside the foreach clause before the sql query definition. Also, verify that $UpIP is just an IP address and not a more complex object. Try looking at $Results[0] to verify.

Foreach ($UpIp in $Results)
{
$ModIP = ($UpIP.Split('.') | foreach {"0:000}" -f [int]$}) -join '.'
$Sqlserver = 'popsql2k8'
$Sqlcatalog = 'netops'
$SqlQuery = "SELECT host from dbo.View_DNSxDHCP WHERE dns_ip_alias = '$ModIp'"

$Relults is an array of strings which are the IP addresses.

Boo on me! A typo when copying it across from my test. Sorry about that. This is correct:

$ModIP = ($UpIP.Split('.') | foreach {"{0:000}" -f [int]$}) -join '.'

Thanks for all of your help! That does the trick. I don’t know why I was missing that…or why my brain had a meltdown when trying to convert the addresses. Thanks again!
