Comparing two arrays (ip values ranges/subnets etc)

I'm trying to use two arrays to compare ipsubnets and ip-ranges but can't seem to work out why when I try comparing say "192.168.0.10 - 192.168.10 against "10.152.0.1-10.152.0.10 the script reports a match? Can anyone shed what I'm missing?

function get_data
{
    $wmi = gwmi -Namespace "root\sms\site_XXX" -Class sms_boundary -Filter "boundarytype='3'" | Select-Object -ExpandProperty value
           $Target= @()
    foreach($i in $wmi)
    {
        $target += $i    
    }
    $wmi = gwmi -Namespace "root\sms\site_XXX" -Class sms_boundary -Filter "boundarytype='0'" | Select-Object -ExpandProperty value
           $Target1= @()
    foreach($i1 in $wmi)
    {
        $target1 += $i1    
    }

    foreach($first in $Target)
    {
    if($Target1 -contains $first)
        {
            write-host "No Overlap First not in second array" $first
        }
        else
        {
            write-host "Overlap First in second array"  $first
        }
    }
    foreach($first1 in $Target1)
    {
    if($Target -contains $first1)
        {
            write-host "No Overlap First not in second array" $first1
        }
        else
        {
            write-host "Overlap First in second array"  $first1
        }    
    }
}
