Moving your mobile customers from IPv4 to IPv6
Holger Metschulat

Between 2015 and 2021, in Germany, Deutsche Telekom has first enabled Dualstack IPv4 and IPv6 for their mobile subscribers, and then successfully transitioned most of them into an IPv6-only access model.

This talk will highlight the rationale, the planning phase, the different testing stages as well as the implementation and the migration of the customer base.

You will also learn some basics on how IPv6 works in 3GPP mobile networks, and a lot of lessons learnt will be shared.
