Property Value

DuplicateAddressDetectionState

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

Attributes: SupportedOSPlatformAttribute

Exceptions

PlatformNotSupportedException

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

Remarks

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.
