IPv6 Stateless Address Autoconfiguration for Satellite Networks using Topology-Embedded Interface Identifiers

This document specifies a Stateless Address Autoconfiguration (SLAAC) mechanism tailored for satellite constellation networks. It describes how a Host generates IPv6 Interface Identifiers (IIDs) based on deterministic orbital topology parameters and spacecraft identifiers, rather than hardware Media Access Control (MAC) addresses. By embedding topological information (Shell, Orbit, Satellite Index) directly into the IID, this method provides semantic addressing, allowing network operators and routing protocols to derive physical location information solely from the IPv6 address. This approach guarantees global uniqueness within the constellation, minimizes the need for Duplicate Address Detection (DAD), and is suitable for Links typically found in space environments, such as CCSDS AOS or space- based Ethernet.
