Assistance with script to find IP and Mac Address from a list of computer.txt

hello,

i have working script gives me need...but it's writing out in triplicate of computers , can't see why?  can see i've done wrong in code cause this:

[cmdletbinding()]  param (   [parameter(valuefrompipeline=$true,valuefrompipelinebypropertyname=$true)]      [string[]]$computername = $env:computername  )                begin {}  process {   foreach ($computer in (gc .\computers.txt)) {    if(test-connection -computername $computer -count 1 -ea 0) {     $networks = get-wmiobject win32_networkadapterconfiguration -computername $computer | ? {$_.ipenabled}     foreach ($network in $networks) {      $ipaddress  = $network.ipaddress          $macaddress  = $network.macaddress      $outputobj  = new-object -type psobject      $outputobj | add-member -membertype noteproperty -name details -value $computer.toupper(), $ipaddress, $macaddress      $outputobj      }    }   }  }                end {}

the results show follows:

as can see, pc name pcnum2 shows 3 times.

any appreciated.

if run

get-wmiobject win32_networkadapterconfiguration -computername pcnum2 | ? {$_.ipenabled}

...do 3 adapters?

is pcnum2 included more once in .\computers.txt?

i rid of pipeline stuff well: begin, process , end blocks... looks it's not being used.

prove can results want before getting clever it.

i create object , use method... (just example... )

#this array definition goes @ beginning... outside loop
$existingdata=@() 
#within loop, add new object existing array
$existingdata+=new-object psobject -property @{'computer'=$computer;'ip'=$network.ipaddress;'mac'=$network.macaddress} 

$existingdata contains collected data
