Vista - Locate MAC from IP with WMI

I have an IP and i want to get the assocaited MAC address to it. I'd like to
do this with WMI so i can easily remote to systems but the IP address in any
WMI class is an array. I have the IP as a string.

Thanks
Justin

11# $ipa | % { write-output "$_ $(nbtstat -a $_ |
select-string 'MAC Address')" }
172.16.15.117 MAC Address = 00-50-56-8A-39-18
172.16.15.48 MAC Address = 00-50-56-8A-43-81

As I said, quick & dirty.

You can check http://scriptolog.blogspot.com/2007/...c-address.html
It doesn't retrieve the MAC through WMI but sure can help.
Be sure to check the comment from Jeff which suggests another cool method.

IPAddress,MACAddress

IPAddress MACAddress
--------- ----------
{209.134.176.14} 00:15:C5:53:99:53
{209.134.176.14} 00:15:C5:53:99:53

Notes:
1. gwmi = Get-WmiObject
2. Several diff ways to get your IPs into $ip...ask if you need help on
that.

Thanks for the replies guys...

Because of the way this network runs (no ICMP) a lot of that stuff wont
work... i did however figure this out after some digging...

here is the onliner i came up with.. works well

(gwmi win32_networkadapterconfiguration | where {$_.ipaddress -eq
$theip}).macaddress

Thanks
Justin
