A tree structure is not at all needed. What is needed is more aggregation.
Please see the definitive mathematical analysis of routing scaling via
aggregation:
Leonard Kleinrock and Farouk Kamoun, "Hierarchical Routing for Large
Networks: Performance Evaluation and Optimization",
Computer Networks 1 (1977), North-Holland Publishing Co., pp. 155-174.
which explains this all clearly.

"Cazart!", as Hunter Thompson would say.
So perhaps what we really need, instead of IPv6, is something that looks less
like IPv4 (with a few fields made larger).
