Unformatted text preview: ve a 64-bit interface ID field (i.e., n + m = 64), formatted as described in Section 2.5.1. start with Global Unicast addresses that binary 000 have no such constraint on the size or structure of the interface ID field. Examples of Global Unicast addresses that start with binary 000 are the IPv6 address with embedded IPv4 addresses described in Section 2.5.5. value An example of global addresses starting with a binary other than 000 (and therefore having a 64-bit interface ID field) can be found in [GLOBAL]. 2.5.5. IPv6 Addresses with Embedded IPv4 Addresses Two types of IPv6 addresses are defined that carry an IPv4 address in the low-order 32 bits of the address. Compatible These are the "IPv4- IPv6 address" and the "IPv4-mapped IPv6 address". IPv4-Compatible IPv6 Address The "IPv4-Compatible IPv6 address" was defined to assist in the IPv6 transition. is as The format of the "IPv4-Compatible IPv6 address" follows: | | 80 bits | 16 | 32 bits +-------------------------------------+-------------------...
