in the most recent architecture, rfc 4291, that was deprecated. The exact statement is
2.5.5.1. IPv4-Compatible IPv6 Address The "IPv4-Compatible IPv6 address" was defined to assist in the IPv6 transition. The format of the "IPv4-Compatible IPv6 address" is as follows: | 80 bits | 16 | 32 bits | +--------------------------------------+--------------------------+ |0000..............................0000|0000| IPv4 address | +--------------------------------------+----+---------------------+ Note: The IPv4 address used in the "IPv4-Compatible IPv6 address" must be a globally-unique IPv4 unicast address. The "IPv4-Compatible IPv6 address" is now deprecated because the current IPv6 transition mechanisms no longer use these addresses. New or updated implementations are not required to support this address type. I should think you are within bounds to not announce it at all. On Feb 4, 2008, at 6:09 AM, snort bsd wrote:
Hi all:With IPv4-compatible IPv6 address space, could I aggregate the address space?say 192.168.0.0/16 become ::192.168/112? or It must be converted to native IPv6 address space?Just wondering,Get the name you always wanted with the new y7mail email address.www.yahoo7.com.au/y7mail
