After reading Mikael's email pointing to a 3gpp spec of late 2014
mandating DHCPv6-PD to both UE and core network - I must say I am
optimistic about the arrival of DHCPv6-PD to cellular network operators.

Currently, some cellular networks already offer DHCPv6 together with
SLAAC.  Technically that DHCPv6 is extremely simple to upgrade to DHCPv6-PD.

My question is when?

I can speculate it will be in late 2016.  Because 4G was in specs 2
years before trial deployments.

poisonous than you present.
