>     This document has analyzed five GPRS and two IMS IPv6 transition 
>     scenarios. Numerous 3GPP networks are using private IPv4 
> addresses 
>     today, and introducing IPv6 is an important thing. The two first 
>     GPRS scenarios and both IMS scenarios are seen the most relevant. 
>     The authors summarize some main recommendations here: 
>        - Dual-stack UEs are recommended instead of IPv4-only or IPv6-
>          only UEs. It is important to take care that the applications 
>          in the UEs support IPv6. IPv6-only UEs can become feasible 
>          when IPv6 is widely deployed in the networks, and most 
>          services work on IPv6. 
>        - It is recommended to activate an IPv6 PDP context when 
>          communicating with an IPv6 peer node and an IPv4 PDP context 
>          when communicating with an IPv4 peer node. 
>        - IPv6 communication is preferred to IPv4 communication going 
>          through IPv4 NATs to the same dual stack peer node. 
>        - This document strongly recommends the 3GPP operators 
> to deploy 
>          basic IPv6 support in their GPRS networks as soon as 
> possible.

>        - A tunneling mechanism in the UE may be needed during 
> the early 
>          phases of the IPv6 transition process. A lightweight, 
>          automatic tunneling mechanism should be standardized in the 
>          IETF. 
>        - Tunneling mechanisms can be used in 3GPP networks, and only 
>          generic recommendations are given in this document. More 
>          details can be found, for example, in [ISP-sa]. 
>        - We recommend that a detailed solution for the general
