How to Implement This?
Customers could be provisioned only with IPv6
potentially offered as a different tier of service
assume “upgraded” home Internet Gateway Device
/56 prefix, no global IPv4 on the WAN IGD port
Double NAT for legacy home devices
legacy home devices will get RFC1918 addresses assigned by the home gateway
those addresses will be translated to IPv6 by the home gateway…
…and translated back to IPv4 within the service provider network

Native IPv6 service is offered for new devices
