Hi,
Would there be interest to hear about stateless IPv6 prefix delegation proposal - i.e. prefix delegation like in 6RD/6to4, but without encapsulation:
This approach would make it easy to delegate (mainly slightly) shorter than /64 prefixes for a large number of devices connected via point-to-point links (e.g. cellulars). The con is extra consumption on IPv6 address space. I think the approach would be
useful if many devices would need few additional /64s, but would not compete with flexibility of RFC3633.
Best regards,
Teemu
