As far as I'm aware Android still today does not support DHCPv6.

From what I remember this is due to the current requirement for multiple ipv6 subnets for various applications (vpns among others) to function correctly. As a result Google has disabled Android from receiving a DHCP lease as it wasn't long enough. if you look back about 6 months there is probably 100+ posts on the subject. All I really know is that I can not provide an ipv6 dhcp lease to an android phone and have it receive the address. james On Fri, Jul 22, 2016 at 1:54 AM, Ricardo Ferreira < ricardofbferre...@gmail.com> wrote: > Is there anyone here working in an ISP where IPv6 is deployed? > We are starting to plan the roll-out IPv6 to mobile subscribers (phones) I > am interesting in knowing the mask you use for the assignment; whether it > is /64 or /128. > > In RFC 3177, it says: > 3.
