The network interfaces on a computer provide network connectivity. Network interfaces are also known as network adapters.
The following code example displays Domain Name Service (DNS) configuration information for the local computer's network adapters.
Public Shared Sub DisplayDnsConfiguration()
Dim adapters As NetworkInterface() = NetworkInterface.GetAllNetworkInterfaces()
Dim adapter As NetworkInterface
For Each adapter In adapters
Dim properties As IPInterfaceProperties = adapter.GetIPProperties()
Console.WriteLine(adapter.Description)
Console.WriteLine(" DNS suffix................................. :{0}", properties.DnsSuffix)
Console.WriteLine(" DNS enabled ............................. : {0}", properties.IsDnsEnabled)
Console.WriteLine(" Dynamically configured DNS .............. : {0}", properties.IsDynamicDnsEnabled)
Next adapter
End Sub 'DisplayDnsConfiguration
public static void DisplayDnsConfiguration()
{
NetworkInterface[] adapters = NetworkInterface.GetAllNetworkInterfaces();
foreach (NetworkInterface adapter in adapters)
{
IPInterfaceProperties properties = adapter.GetIPProperties();
Console.WriteLine(adapter.Description);
Console.WriteLine(" DNS suffix .............................. : {0}",
properties.DnsSuffix);
Console.WriteLine(" DNS enabled ............................. : {0}",
properties.IsDnsEnabled);
Console.WriteLine(" Dynamically configured DNS .............. : {0}",

Console.WriteLine();
