get MAC and IP of my NIC card

[sambo]

I am trying to find the IP address associated with a particular NIC card. If a PC has more than 1 NIC card, then it can have more than 1 IP address.

So... given a particular IP address, how can I find the MAC (or NIC card) associated with that IP?

Here is what I have so far... its close, but not quite there.

NetworkInterface[] adapters = NetworkInterface.GetAllNetworkInterfaces();
foreach (NetworkInterface adapter in adapters)
{
    //could have multiple MAC addresses
    lstOutput.Items.Add("MAC : " + adapter.GetPhysicalAddress());
}

lstOutput.Items.Add("Host Name : " + Dns.GetHostName());

IPAddress[] hosts = Dns.GetHostAddresses(Dns.GetHostName());
foreach (IPAddress address in hosts)
{
    //could have multiple IPs (how do I associate with the correct MAC?)
    lstOutput.Items.Add("Address : " + address.ToString());
}
