  2. Outline • Introduction • NAT64-CPE Mode Scenario Overviews • NAT64-CPE Mode Operation • NAT64-CPE Approach Discussion

  3. Introduction • The document has proposed an approach of NAT64-CPE mode, which would give residential service opportunities to be accessed by remote subscribers going through IPv6 networks. • The document captures the fundamental NAT64 functionalities with special cares to fit into CPE scenarios and don't need cooperate with DNS64 any more

  4. NAT64-CPE Mode Scenario Overviews • IPv6-only client attached to a dual-stack network, but the destination server is running on a private site where there is NAT64-CPE numbered with public IPv6 addresses and private IPv4 addresses.

  5. NAT64-CPE Mode Operation • CPE Functionalities Description • It will perform the functionalities that normal CPE does except NAT44 forwarding • CPE should carry NAT64 capable mode without integrating DNS64; The NAT64 IPv6 prefix will be NSP; And, ISP will reserve distinct NSP for each CPE • DNS Configuration Consideration • Each residential services should be represented by FQDN format. The corresponding naming resource record should be stored as AAAA.
