Our APNs are ready for IPv6. Meanwhile most of current modules also support IPv6, with exception of some using 1st generation platforms.

In case of public APN, we are using a NAT service to allocate public IP addresses dynamically. In case of a private APN, devices get IP addresses from the internal IP addresses space. The IP address assignment is usually managed by Deutsche Telekom. However, the customer has the possibillity to operate his own AAA system (RADIUS forwarding) so that they can manage the IP address assignment by themself.

Hi Robin, NB-IoT with an IP connection will be available in the summer. But, I will reach out to you next week to learn and find out together how we can make your downlinks easier in the current situation.
