Transporting IP Over DUAL - PR_IP

One of our original desires in designing a new Link layer was to provide a better Link layer for the transmission of TCP/IP packets over amateur packet radio. Apart from the already described goals of reducing headers, we also wanted to remove the need for using ARP and RARP. To do this, we decided to use full or partial IP addresses as the Link address when transmitting IP packets. Partial IP addresses can be used when the size of the subnet serviced by the amateur packet link is known.

For both the protocol values PR_IP and PR_CIP, the size and format of the source and destination addresses are as described in the next section. Note that the source and destination addresses specified in these fields denote the source and destination of the packet on the current link, and may be different to the original source of the packet or its final destination.
