Ejemplos
En el ejemplo de código siguiente se muestra la información de dirección DHCP de las interfaces de red en el equipo local.
void DisplayDhcpServerAddresses()
{
Console::WriteLine( "DHCP Servers" );
array<NetworkInterface^>^adapters = NetworkInterface::GetAllNetworkInterfaces();
System::Collections::IEnumerator^ myEnum19 = adapters->GetEnumerator();
while ( myEnum19->MoveNext() )
{
NetworkInterface ^ adapter = safe_cast<NetworkInterface ^>(myEnum19->Current);
IPInterfaceProperties ^ adapterProperties = adapter->GetIPProperties();
IPAddressCollection ^ addresses = adapterProperties->DhcpServerAddresses;
if ( addresses->Count > 0 )
{
Console::WriteLine( adapter->Description );
System::Collections::IEnumerator^ myEnum20 = addresses->GetEnumerator();
while ( myEnum20->MoveNext() )
{
IPAddress^ address = safe_cast<IPAddress^>(myEnum20->Current);
Console::WriteLine( " Dhcp Address ............................ : {0}",
address );
}
Console::WriteLine();
}
}
}
public static void DisplayDhcpServerAddresses()
{
Console.WriteLine("DHCP Servers");
NetworkInterface[] adapters = NetworkInterface.GetAllNetworkInterfaces();
foreach (NetworkInterface adapter in adapters)
{
IPInterfaceProperties adapterProperties = adapter.GetIPProperties();
IPAddressCollection addresses = adapterProperties.DhcpServerAddresses;
if (addresses.Count >0)
{
Console.WriteLine(adapter.Description);
foreach (IPAddress address in addresses)
{
Console.WriteLine(" Dhcp Address ............................ : {0}",
address.ToString());
}
Console.WriteLine();
}
}
}
Public Shared Sub DisplayDhcpServerAddresses()
Console.WriteLine("DHCP Servers")
Dim adapters As NetworkInterface() = NetworkInterface.GetAllNetworkInterfaces()
Dim adapter As NetworkInterface
For Each adapter In adapters
Dim adapterProperties As IPInterfaceProperties = adapter.GetIPProperties()
Dim addresses As IPAddressCollection = adapterProperties.DhcpServerAddresses
If addresses.Count > 0 Then
Console.WriteLine(adapter.Description)
Dim address As IPAddress
For Each address In addresses
Console.WriteLine(" Dhcp Address ............................ : {0}", address.ToString())
Next address
Console.WriteLine()
End If
Next adapter

Comentarios
El Protocolo de configuración dinámica de host (DHCP) permite a un equipo obtener una dirección de red de un servidor DHCP, en lugar de usar una dirección de red estática (fija). Un servidor DHCP no asigna permanentemente direcciones; en su lugar, usa temporalmente una de varias direcciones disponibles para el equipo.
