i need to get the ip addresses of a uut, i do this command

$IPconfig = invoke-command -scriptblock {ipconfig /all} -computername $global:uutName -credential $global:Credential
$IPconfig[18] is
IPv4 Address. . . . . . . . . . . : 192.xxx.x.xxa(Preferred)
$IPconfig[38] is
IPv4 Address. . . . . . . . . . . : 192.xxx.x.xxb(Preferred)

how do i get the ip addresses that are between ": " and "(Preferred)"
i was going to hard code it but the ip length can change

First off, start using .NET objects with PowerShell instead of string manipulation! :slight_smile: You can get the IP addresses using the Win32_NetworkAdapterConfiguration WMI class, (lots of other information, too):
PS > Get-WMIObject -Class Win32_NetworkAdapterConfiguration -ComputerName . -Filter {IPEnabled = "True"} | Select-Object Description, IPAddress

Description IPAddress
----------- ---------
Broadcom NetXtreme Gigabit Ethernet {10.x.x.29}
VMware Virtual Ethernet Adapter for VMnet1 {192.168.111.1, fe80::b40a:99a6:a50d:c1c}
VMware Virtual Ethernet Adapter for VMnet8 {192.168.227.1, fe80]
Or, if you’re using v3, use the Get-NetworkConnectionInfo cmdlet:
PS > Get-NetworkConnectionInfo


Name : Broadcom NetXtreme Gigabit Ethernet
DnsServers : {10.x.x.254, 10.x.x.157, 10.x.x.127}
IPAddresses : {10.x.x.29}

ObjectState : Unchanged

Name : VMware Virtual Ethernet Adapter for VMnet8
DnsServers : {}
IPAddresses : {192.168.227.1, fe80::5c71:f473:4ff1:83c5}
AdapterGuid : 1a77e468-d612-4e49-9ccf-489e82a1a54c

But if you just really want to use ipconfig, you’ll have to do some fancy string manipulation and get to know regex…

thanks that makes sense but i still need to extract the ip address because i’m getting the info from a remote server
when i run your command remotely

$IPconfig = invoke-command -scriptblock {Get-WMIObject -Class Win32_NetworkAdapterConfiguration -Filter {IPEnabled = "True"} | Select-Object IPAddress } `
-computername $global:uutName -credential $global:Credential

i get this result

IPAddress PSComputerName RunspaceId
--------- -------------- ----------
{192.168.x.xxx, fe80::5c64:4246:xxx:xxx} stg-xx 4dxxx2-f9xx-xxx-98df-1c4c33xxxx
{192.168.x.xxx, fe80::b88c:87a:xxx:xxx} stg-xx 4dfxxx2-f9xx-xxx-98df-1c4cxxx

$IPconfig.IPAddress will give you the entire array of IP addresses from each computer, ({192.168.x.xxx, fe80::5c64:4246:xxx:xxx}).

You can address each address using the array index: $IPconfig.IPAddress[0] would get you "192.168.x.xxx" and $IPconfig.IPAddress[1] would get you "fe80::5c64:4246:xxx:xxx"
