Question

With PowerShell 2.0 if I run the following on a Windows 7 machine:

(Get-WmiObject Win32_NetworkAdapterConfiguration |
    Where { $_.IPAddress }

it returns

192.168.83.26
fe80::<IPv6 address>

If I run:

(Get-WmiObject Win32_NetworkAdapterConfiguration |
    Where { $_.IPAddress }.ToString()

It returns

System.Object[]

Why? And how can I resolve it?

FYI, I’m actually trying to use .ToString().split('.')[0..2] -join '.' but I’m pretty sure it’s the .ToString that’s causing the issue

---

function Get-IPAddress{
(Get-WmiObject Win32_NetworkAdapterConfiguration |
    Where { $_.IPAddress } |
Select -Expand IPAddress).split('.')[0..2] -join '.'
}
Get-IPAddress

returns 192.168.10 on PoSh 3. This doesn’t seem to work on PoSh 2, and returns the `System.Object[]’ that I stated above. The error complains about not having a Method named trim. Others have suggested declaring it as a String, but I’ve been unable to make it work

Answer 1

Try this:

(Get-WmiObject Win32_NetworkAdapterConfiguration | 
? { $_.IPAddress } ).ipaddress | % { ($_ -split '\.')[0..2]}

This:

(Get-WmiObject Win32_NetworkAdapterConfiguration | ? { $_.IPAddress } ).ipaddress 

returns always an array of strings also in the case of a single ip address.
