IEEE Std 802.16 is an air interface specification for fixed and
mobile Broadband Wireless Access Systems. Service-specific
convergence sublayers to which upper-layer protocols interface are a
part of the IEEE 802.16 MAC (Medium Access Control). The Packet
convergence sublayer (CS) is used for the transport of all packet-
based protocols such as Internet Protocol (IP) and IEEE 802.3 LAN/MAN
CSMA/CD Access Method (Ethernet). IPv6 packets can be sent and
received via the IP-specific part of the Packet CS. This document
specifies the addressing and operation of IPv6 over the IP-specific
part of the Packet CS for hosts served by a network that utilizes the
IEEE Std 802.16 air interface. It recommends the assignment of a
unique prefix (or prefixes) to each host and allows the host to use
multiple identifiers within that prefix, including support for
randomly generated interface identifiers. [STANDARDS-TRACK]
