You can get all of this information using the System.Management classes,
which basically provide a wrapper around thw WMI APIs. In particular, you'd
want to query against the Win32_NetworkAdapterConfiguration class:

http://msdn.microsoft.com/library/en-us/wmisdk/wmi/win32_networkadapterconfigu...

For example, the following code will produce a list of the MAC Addresses for
all NIC cards on the local machine.

//////// CODE START
ManagementObjectSearcher query = new ManagementObjectSearcher("SELECT * FROM
Win32_NetworkAdapterConfiguration") ;
ManagementObjectCollection queryCollection = query.Get();

ArrayList addresses = new ArrayList();
foreach (ManagementObject mo in queryCollection)
{
if (mo["MacAddress"] != null)
addresses.Add(mo["MacAddress"].ToString());
}
macAddresses = (string[]) addresses.ToArray(typeof(string));
//////// CODE END

The link above shows you all the properties for the
Win32_NetworkAdapterConfiguration object, which includes a property for
their IPAddresses.

Hope that helps -
Ken
