Hi Anne,
Thanks for the clarification. I was concerned that the operation would
be too complex if 65,536*/64 registrations would be considered as a
single /48 assignment, but it is cleared from your explanation.
Just to confirm, I have put my understanding into a diagram. Please
let me know if I have the wrong picture.
<Registrations in Registry DB>
The case below would be considered as 3*/48 assignments
<-----/48------><-----/48------><-----/48------><-----/48------>
|--------------||--------------||--------------||--------------|
X XX XXX XX XX
X= assignments longer than /48
The basic idea is that the utilization is calcuated on /48 address
range basis as stated in the policy, but DB registration ranges do
not necessarily need to match as they are for POCs purpose.
I think this makes sense and understand that some LIRs prefer to
register enduser assignments rather than making a single /48
registration as their infrastructure for the POC purpose.
I'm still not too convinced about registering hosts though. The
entries in the DB would be enormous if such registrations are
made. I'm not sure it's worth securing the DB resources to publicly
support it by specifying in the document. At the bottom line, I agree
that there is no big harm since it's optional, and it's okay to
support it case by case in the actual operation.
Best Regards,
Izumi
