Here is some info on how IPv6 operates
A router on the local link sends network-type information, such as the prefix of the local link and the default route, to all its nodes.
An IPv6-enabled host appends its 64-bit link-layer address to the 64-bit local link prefix to autoconfigure itself.
The host 64-bit extended universal identifier (EUI) address format results from the original 48-bit MAC address plus a 16-bit 0xFFFE inserted into the middle.
This autoconfiguration produces a full 128-bit address that is usable on the local link and guarantees global uniqueness. IPv6 will detect duplicate addresses in special circumstances to avoid address collision.
The host sends an RS at boot time to request a router to send an immediate RA on the local link.
The host then receives the autoconfiguration information without waiting for the next scheduled RA.
The RA message includes the prefix for the link, and also gives the host the lifetime of the prefix.
