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
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.
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.
NAT64-CPE Mode Operation Example
NAT64-CPE Approach Discussion
• NAT64-CPE is capable of making residential server to be accessed, by means of which users could visit the IPv4-only server remotely
• NAT64-CPE is a solely NAT64 deployed solution in CPE environment. It will compatible with legacy residential servers and no further updates requirements to DNS
