It is not. Though IPv6 was designed against OSI CLNP (with 20B,
or, optionally, 40B addresses), IPv6 incorporated many abandoned
ideas of CLNP and XNS already known to be useless or harmful with
experiences on IPv4 to be a protocol as bad as or even worse than

For example, address length was extended from original 8B to
16B to allow lower 48bits be MAC addresses, which was what
XNS was doing, only to make ISP operations with raw
addresses prohibitively painful.
