ARINC Specification 664P4-2:2007

This specification defines the addressing plan and rules for addressing used in Aircraft Data Networks (ADN). The plan is organized in accordance with the seven-layer Open Systems Interconnection (OSI) Reference Model. The specification sets forth the structure of addresses that are employed in the ADN and guidance for address determination. This guidance ensures that all applications - that use this address structure to send messages - can know the address structure of the destination(s) at configuration-time.
