Hi,
I'm new here.
I just want to ask a question.
All of us know that all networking companies running to wireless technology,
and as I understand there is lot of electronic machines will have IPv6
address in the future like TV, ....etc. and the most important is the Future
GSM, if all mobiles have IPv6 address so we can not think about hierarchy
levels at all. Also PALM. because if I travel with my mobile from one
country to another, I need a roaming in current technology, but in the
future there is no roaming I think there will be like just register this
IPv6 address with Telco. company in the country i went and it maybe
automatically because of new features in the IPv6 [auto addressing]!!.
I just ask because I dont have a complete answer for this.
Regards
Faisal Al-Jundi

Huh?
As I wrote:

There is no need to make the figure a power of 2.

If the company request 200 IDs, the one-layer-up entity can delegate
exactly 200 IDs.
Or, if the the one-layer-up entity think 200/256 large enough (I think
this is the case), it can delegate 256 IDs.

No.
Read the following sentense, again and again.

^^^^^^^^^^
