Android is getting DHCPv6 (-PD) support. If you want to use it, be prepared to scrap your current addressing plans - each Android device will now consume a /64 on its own.

@Oskar456 I can't get out of my head that Android doesn't support DHCPv6!
Why, why does it want /64? Some cases are legit but, frankly, *always*?

@gvlx It is definitely wrong to have a network set up in a way that one host can get only one IPv6 address. Nobody should be forced to do NAT on IPv6 just to conserve the number of used addresses.
Using Prefix Delegation to the device is a great idea, definitely better than cherrypicking tens of addresses from a shared SLAAC segment.
However, the requirement to have a prefix of /64 for each device does not seem right. It's just copying the same broken design from 3GPP networks.
