IPAddress.MapToIPv6 Method


Maps the IPAddress object to an IPv6 address.

 System::Net::IPAddress ^ MapToIPv6();
public System.Net.IPAddress MapToIPv6 ();
member this.MapToIPv6 : unit -> System.Net.IPAddress
Public Function MapToIPv6 () As IPAddress



Returns IPAddress.

An IPv6 address.


Dual-stack sockets always require IPv6 addresses. The ability to interact with an IPv4 address requires the use of the IPv4-mapped IPv6 address format. Any IPv4 addresses must be represented in the IPv4-mapped IPv6 address format which enables an IPv6 only application to communicate with an IPv4 node. The IPv4-mapped IPv6 address format allows the IPv4 address of an IPv4 node to be represented as an IPv6 address. The IPv4 address is encoded into the low-order 32 bits of the IPv6 address, and the high-order 96 bits hold the fixed prefix 0:0:0:0:0:FFFF. The IPv4-mapped IPv6 address format is specified in RFC 4291. For more information, see www.ietf.org/rfc/rfc4291.txt.
