IPAddressInformation Class
Provides information about a network interface address.
System.Net.NetworkInformation.IPAddressInformation
System.Net.NetworkInformation.MulticastIPAddressInformation
System.Net.NetworkInformation.UnicastIPAddressInformation
Namespace: System.Net.NetworkInformation
Assembly: System (in System.dll)
The IPAddressInformation type exposes the following members.
| 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). |
| 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 a hash function for a particular type. (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.) |
You do not create instances of this class; instances are returned by methods in the IPInterfaceProperties class.
The following code example displays the Domain Name Service (DNS) addresses for the network interfaces on the local computer.
public static void DisplayDnsAddresses() { NetworkInterface[] adapters = NetworkInterface.GetAllNetworkInterfaces(); foreach (NetworkInterface adapter in adapters) { IPInterfaceProperties adapterProperties = adapter.GetIPProperties(); IPAddressCollection dnsServers = adapterProperties.DnsAddresses; if (dnsServers.Count > 0) { Console.WriteLine(adapter.Description); foreach (IPAddress dns in dnsServers) { Console.WriteLine(" DNS Servers ............................. : {0}", dns.ToString()); } Console.WriteLine(); } } }
Windows 8, Windows Server 2012, Windows 7, Windows Vista SP2, Windows Server 2008 (Server Core Role not supported), Windows Server 2008 R2 (Server Core Role supported with SP1 or later; Itanium not supported)
