Duplicate IP Address Detection for IPv6

In dual stack systems, such as Windows CE .NET 4.1 and later, the DNS name resolution may yield both IPv4 and IPv6 addresses. Algorithms are used to determine source and destination addresses of appropriate scope and configuration status, thus determining which stack (IPv4 or IPv6) to use. For more information, see Default Address Selection for IPv6.
In IPv6, Neighbor Discovery determines that an address considered for use is not already in use by a neighboring node. This is equivalent to the use of gratuitous ARP frames in IPv4. For more information, see Neighbor Discovery (ND).
