IPAddressInformation Class

.NET Framework (current version)

Provides information about a network interface address.

Namespace: System.Net.NetworkInformation
Assembly: System (in System.dll)

Inheritance Hierarchy

System::Object
System.Net.NetworkInformation::IPAddressInformation
System.Net.NetworkInformation::MulticastIPAddressInformation
System.Net.NetworkInformation::UnicastIPAddressInformation

Syntax

C++

public ref class IPAddressInformation abstract

Constructors

	Name	Description
	IPAddressInformation()	Initializes a new instance of the IPAddressInformation class.

Properties

	Name	Description
	Address	Gets the Internet Protocol (IP) address.
	IsDnsEligible	Gets a Boolean value that indicates whether the Internet Protocol (IP) address is valid to appear in a Domain Name System (DNS) server database.
	IsTransient	Gets a Boolean value that indicates whether the Internet Protocol (IP) address is transient (a cluster address).

Methods

	Name	Description
	Equals(Object^)	Determines whether the specified object is equal to the current object.(Inherited from Object.)
	Finalize()	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection.(Inherited from Object.)
	GetHashCode()	Serves as the default hash function. (Inherited from Object.)
	GetType()	Gets the Type of the current instance.(Inherited from Object.)
	MemberwiseClone()	Creates a shallow copy of the current Object.(Inherited from Object.)
	ToString()	Returns a string that represents the current object.(Inherited from Object.)

Remarks

You do not create instances of this class; instances are returned by methods in the IPInterfaceProperties class.

Examples

The following code example displays the Domain Name Service (DNS) addresses for the network interfaces on the local computer.

C++

void DisplayDnsAddresses()
{
   array<NetworkInterface^>^adapters = NetworkInterface::GetAllNetworkInterfaces();
   System::Collections::IEnumerator^ myEnum11 = adapters->GetEnumerator();
   while ( myEnum11->MoveNext() )
   {
      NetworkInterface ^ adapter = safe_cast<NetworkInterface ^>(myEnum11->Current);
      IPInterfaceProperties ^ adapterProperties = adapter->GetIPProperties();
      IPAddressCollection ^ dnsServers = adapterProperties->DnsAddresses;
      if ( dnsServers->Count > 0 )
      {
         Console::WriteLine( adapter->Description );
         System::Collections::IEnumerator^ myEnum12 = dnsServers->GetEnumerator();
         while ( myEnum12->MoveNext() )
         {
            IPAddress ^ dns = safe_cast<IPAddress ^>(myEnum12->Current);
            Console::WriteLine( "  DNS Servers ............................. : {0}", 
               dns->ToString());
         }
      }
   }
}
