Hi,

So let me try to shed some light on what we are thinking in Telenor Norway.

Even though we have launched an IPv6-only APN, our main strategy for the home network is to support the Ext. PDP type. Also, both our fixed and mobile network architectures are based on DS.

We are currently working on putting the final pieces together for enabling DS. Roaming brokeness caused by the ext. PDP is a major concern for us. DS will affect our whole customer base, so it will take a while with testing before we are comfortable launching this.

Telenor Norway has been piloting NAT64/464XLAT for some time now with no major issues. We see that we need to support all scenarios for mobile devices, i.e. IPv4-only, IPv6-only and DS. We chose to launch IPv6 on a few selected devices as a gradual introduction of IPv6 in our mobile network.  By enabling IPv6-only on a few handsets, we can identify those mobile operators that do not support IPv6-roaming and we use this opportunity to contact them through commercial and technical channels, urging them to enable IPv6 support on their SGSN. If this is unsuccessful, we will consider steering the roaming traffic away from those operators during a transition period if necessary. We believe it is important to take an active stand on this instead of waiting for everyone to get around to enable IPv6. As many people on the mailing list have mentioned, there are cases where roaming on IPv6 fails. This is also our experience, but it is something we are willing to accept. 

As Tore has mentioned, our customers are free to use one of our IPv4-only APNs, however, we have not had any such requests.

BR,
