Synthesis mode from ipv4 to ipv6

[caidehen]

As shown in the following figure, ipV4 address is converted to ipv6 address and the last eight bits of the address are concatenated to the prefix. I want to know how this prefix comes from and where can I get the address of this prefix？？？？？？

See RFC5156 section 2.2: IPv4-Mapped Addresses, which references some older RFCs for details.
