This object controls whether or not the destination address is present in the outgoing data stream from a Type A user to the IP interface logic. It is only applicable for UDP type services (see autifService). To handle alternate access operation, the Destination address can be inserted by the alternate access module (see altaHostSupplementalAddr). 'none' - no additional address information is present, and the message is sent to the sockets default destination IP address. 'ip' - this indicates that the first 4 bytes of the data stream holds the IP address of the destination host. For a UDP style socket this address is used in the applications sendto() call. If the address is all zeros, then the message will be sent to the sockets default destination IP address defined in autifRemAddress. On messages sourced from the IP layer, the source IP address is pre-pended to the data stream before it is forwarded to the alternate access module and multiplexor.
