But I think ABK as well as CGA addresses would require communicating in order to verify that the address is valid according to ABK or CGA. Thus in order to choose destination and source addresses the node would need to communicate. Seems kind of expensive. In the case of CGA (I haven't wrapped my head around ABK yet) it seems feasible to do things without a bit in the address for MIPv6 if each time a CN receives a BU, the CN would challenge the MN to prove that it has a public key whose hash (really, hash(PK, prefix, stuff)) is the IID. If the MN can't prove that then either the MN is an imposter or is it using a non-CGA IID. Without a bit in the address the CN can't tell which of those is the case. > 3. require manual configuration.
