Remarks
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 is determined by the address family of the first IP address that resolves to the endpoint when used by a Socket.
