Boeing Phantom Works Mobile Ad-hoc Networks (MANETs) consist of routers operating over multihop wireless links, and may or may not connect to other networks and/or the Internet. Routers in MANETs must have a way to automatically provision local and global-use IP addresses/prefixes. This document specifies mechanisms for MANET autoconfiguration that view the MANET as a virtual ethernet. Both IPv4 and IPv6 are discussed.
