    abstract =  {This memo is a digest of the user network interface specification of NTT Communications' dual stack ADSL access service, which provide a IPv6/IPv4 dual stack services to home users. In order to simplify user setup, these services have a mechanism to configure IPv6 specific parameters automatically. The memo focuses on two basic parameters: the prefix assigned to the user and the addresses of IPv6 DNS servers, and it specifies a way to deliver these parameters to Customer Premises Equipment (CPE) automatically. This memo provides information for the Internet community.},
