a little bit off topic: question regarding IPv6 (in Germany)

[Thomas Schäfer]

Hi,

Thank you for testing, and directing me to documents with 900Pages :-)

One thing is new for me.
Until now I thought the APNs
internet.t-mobile
and
internet.telekom
have the same behavior.
But this is not the case regarding ipv6-only-settings. Could you try 
"internet.telekom" with IPv6/without IPv4?

Regards,
Thomas



PS: very off topic:
Is anybody here from France?

Some feedback regarding implementation, success with ModemManager and so on?
