Hi, Section 4.1 states: "Roaming to IPv4-only networks with IPv6 PDP/PDN request would fail to get addresses." In my experience, this is seldom (if ever) the case. ---> Same experience with other countries (specifically guys from Sweden) visiting the Philippines *but* problems arises with the Billing Systems (TAP format) And it was immediately corrected.... Regards Medel ++++++++++++++++++++++++++++++++++++++++++++++++++++++ -----Original Message----- From: v6ops-bounces@ietf.org [mailto:v6ops-bounces@ietf.org] On Behalf Of Tore Anderson Sent: Thursday, July 18, 2013 8:44 AM To: v6ops@ietf.org Subject: Re: [v6ops] new draft: draft-chen-v6ops-ipv6-roaming-analysis > http://tools.ietf.org/html/draft-chen-v6ops-ipv6-roaming-analysis. Section 4.1 states: "Roaming to IPv4-only networks with IPv6 PDP/PDN request would fail to get addresses." In my experience, this is seldom (if ever) the case. My home network (Network Norway) supports IPv6 PDP context and in recent years I've roamed in more European countries than I can enumerate from the top of my head, in some Mid-East countries, in the U.S., and in Japan. I've made a point out of trying all available PLMNs my phone can see in the air, and I know for a fact that most of them are IPv4-only. In spite of this I cannot recall last time I had a problem establishing IPv6 connectivity when roaming. The way I see it, 3GPP IPv6 roaming is one of those things that Just Works. I'm not an expert on 3GPP network architecture, but as far as I've been able to understand, the reason why this work is that the IPv6 gets tunnelled back to my home network using GTP, and that the visited network just considers the payload as "data" and doesn't really care whether it is IPv4 or IPv6. I'm sure there could be exceptions to the above. I've heard several people suggest that Japan is particularly problematic in this regard - but in my experience it Just Works there, too.
