The DnsEndPoint(String^, Int32) constructor can be used to initialize a DnsEndPoint class using either a host name or a string that represents an IP address and a port. This constructor sets the AddressFamily property to Unknown.
When using this constructor with a host name rather than a string representation of an IP address, the address family of the DnsEndPoint will remain Unknown even after use. The AddressFamily property of any Socket that is created by calls to the ConnectAsync method will be the address family of the first address to which a connection can be successfully established (not necessarily the first address to be resolved).
