10. IANA Considerations

Per this document, IANA has allocated a well-known IPv4 192.0.0.0/29 network prefix. That range is used to number the Dual-Stack Lite interfaces. Reserving a /29 allows for 6 possible interfaces on a multi-home node. The IPv4 address 192.0.0.1 is reserved as the IPv4 address of the default router for such Dual-Stack Lite hosts.
