draft-xli-behave-divi-02-Address-sharing stateless double IVI有这样两段描述
The stateless 1:N IVI keeps the features of stateless, end-to-end
address transparency and bidirectional-initiated communications of
the original stateless 1:1 IVI, while it can utilize the IPv4
addresses more effectively. The stateless 1:N dIVI has above
features and it does not require the DNS64/DNS46 and ALG supports.
Therefore, the IPv6 end systems must follow the port number range
defined by the extended IPv4-translatable addresses. The behavior of
the IPv6 end system when communicating with the IPv4 Internet are:
o If the IPv6 end system is used as a server, different well-known
ports will be served by different IPv6 hosts.
o If the IPv6 end system is used as a client, the end system must
generate the source port numbers in the range defined by the
extended IPv4-translatable address format. This can be done by
modification of the end system, or via a port number mapping
device (home gateway). |
