Maybe. :)

Presumably it would work. But you will not get an IPv6 address or public IPv4 address if you use that SIM card here.

Hmm.. When I use my mobile phone in any EU country, I get a finnish IP address.

I also still have a working austrian SIM card, and if I use it in Finland, I get an austrian IP address.

Ok, Some day I have to check how it goes with IPv6 ...

That assumes some kind of "tunnel" from the mobile device to the "host network" in the home country. With the tunnel endpoint on the mobile device, not on the guest network. Hmm...

The tunnel is made to the server that maintains your credentials and account.
Spreading your credentials and guarding the limits of your account is
probably more complicated.

That's the meta data. Different kettle of fish.

I still don't see how one can have an IPv6 address on the end device if the "last mile" does not support IPv6, other than via a 6to4 tunnel with one of the tunnel end points on the end device.

I do not know what transport GSM uses, But could not the GSM transport be
the Tunnel and carry a vlan to your endpoint.

A quick search shows that GSM is related to SS7. There is no IP in SS7.
So you probably get a IP over XXXXX like with ADSL. It is still all
Telecom world thinking.

When you are roaming you certainly do not get IP access in the country
where you are. You access the net trough the entry point of your provider.

I currently have no active forein Sim cards, so I cannot support my
remarks with real results.

GSM is part of the link layer. Like ISDN. When I used it for data many moons ago, I called a telephone number for Internet access, just like one did with a POTS modem. It was the same number in fact. It was my understanding that there were modem banks in the GSM exchange of the provider.

When you are roaming you certainly do not get IP access in the country where you are. You access the net trough the entry point of your

All they need are two ughm... numbers: IMSI and Ki (ID and key).

However, the operators' billing systems are tied to a contract number:
1. one customer may have many phones (so passport data are non-unique);
2. the customer may require SIM card replacement (change IMSI and Ki);
3. the customer may want to change the number.

Not exactly. They call an URL and presents the phone number and a PIN code to log-in. Apart from that, basically a dial-up connection, yes.

The first years using my dongle, I only got a 10.x.x.x IP number, but later on I got a real, public one. I used it for a few weeks when my ADSL didn't work.

Since I got a new IP every time I reconnected -- and often even when I *was* connected -- I never could use it for any kind of server functions (such as binkd), only for outgoing traffic.

As I mentioned I have an active German SIM. (Nettocom -> E-Plus)

After doing the proper incantations, I finally managed to get my Huawei E153 dongle to make a roaming connection via KPN-NL.

I got a 10.x.x.x IP, but when I make a binkp connection from my point to my home system, binkd told me it was coming from x2f7f024.dyn.telefonica.de [2.247.240.36]. So inded a German IP number.

Doesn't seem very stable to me.

it was perfectly stable... stayed online with the same IP for weeks...

i'll give you props for the nice try at attempting to confuse the postings and what they state at certain points of the conversation...

Methinks it's you that are trying to confuse the discussion. This is exactly what you wrote as a comment to what I posted:

Since I got a new IP every time I reconnected -- and often even
when I
*was* connected -- I never could use it for any kind of server
functions (such as binkd), only for outgoing traffic.

really??? i've always done that as long as i've had a public IP address... it was a simply matter of updating my DDNS entry and that was done by running a tool that stayed in the background and handled the updates automatically... yes, i ran servers on my dialup... most of the time, the new IP spread through the network within minutes... no problem and it worked quite well...

"most of the time, the new IP spread through the network within minutes"

"no problem and it worked quite well"

Remember? No mention at all of two weeks with the same IP.

Alas, this has very little to do with IPv6 (that you don't even seem to have), so EOD from me. Sorry Mr. Moderator.

For intermittent connections like binkp mailer sessions, this would work perfectly well, providing the DDNS record TTLs were sufficiently short (typically, 60 seconds is used, which is a good value for this application), because by the time a DNS lookup is attempted, odds are that the DNS will be up
to date and any cacheing has expired, which is what you want. The odds of an IP change happening in the middle of a binkp session is fairly low, because the
sessions are generally short lived.

Where this sort of system falls down is long lived sessions, so it's more likely to affect telnet users than mailers. User sessions will get interrupted
and eventually time out, and ghosts may be a problem for a while after the IP change.

So, it may or may not be "acceptable", depending on your particular circumstances.
