Basically, IPv6 is XNS IDP.

IDP uses Ethernet's 48-bit address as the basis for its own network
addressing, generally using the machine's MAC address as the primary
unique identifier. To this is added another 48-bit address section
provided by the networking equipment; 32-bits are provided by routers
to identify the network number in the internetwork,
