First, my intent was to use "organization" rather than "LIR" as I wanted
it to be general and apply to both LIRs and end users, that is also why
I moved it out to 6.12. Do you believe only LIR might wnat to reduce
their holdings? You were advocating that end user annual fee be scaled
to holding too, do you want to change the policy when that happens? Let
keep it general and use "organization"
Second, in your #3, what do the retained block(s) have to do with the
reserved space? The retained block(s) are the block(s) kept by the
organization and the reserved space is an ARIN operational issue. I
believe we want the retained block(s) nibble aligned and no smaller than
allowed by policy, /40 for an LIR and /48 for an end user. However, it
would be better not to specify the minimums and get as a reference to
Do you want to allow non-nibble alined blocks to be retained? If you do
then why not just allocate them in the first place.
Or, am I missing something?
