Of course. Hard to argue against imaginary things. :-)


I think "imaginary" is the wrong word here. There's a difference between
imaginary things and leaving room for for future innovation. Phone network
model vs. Internet model is the usual example that comes to mind.


On the other hand, there exist applications *today* that do require
DHCPv6. One such example would be MAP, which IMHO is superior to
464XLAT both for the network operator (statlessness ftw) as well as for
the end user (unsolicited inbound packets work, no NAT traversal
required). MAP is provisioned with DHCPv6 (I-D.ietf-softwire-map-dhcp),
so without DHCPv6 support in Android, MAP support in Android is a
non-starter.


Support for the DHCPv6 protocol, or support for assigning addresses from
IA_NA?
