UnicastIPAddressInformation.DuplicateAddressDetectionState Property


Gets a value that indicates the state of the duplicate address detection algorithm.

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

public abstract DuplicateAddressDetectionState DuplicateAddressDetectionState { get; }

Property Value

Type: System.Net.NetworkInformation.DuplicateAddressDetectionState

One of the DuplicateAddressDetectionState values that indicates the progress of the algorithm in determining the uniqueness of this IP address.

Exception Condition

This property is not valid on computers running operating systems earlier than Windows XP.

To ensure that all network interfaces on a network have a unique address, the interface host is responsible for running a "duplicate address detection" algorithm on unicast addresses. The purpose of this algorithm is to attempt to prevent non-unique addresses on the network. This process is defined in IETF RFC 1971.
