Re: [sig-policy] prop-085: Eligibility for critical infrastructure assig
I'm a bit confused by the whole discussion (I've been away from the list
for a few days, so just catching up).
The final /8 policy comes into force once APNIC has no other IPv4
address space left.
My understanding is that the final /8 policy applies to the final /8 (we
left it to the Secretariat staff to make the operational decision
whether this is an identified /8 block or an equivalent). It supercedes
all other policies for IPv4 address distribution.
And yes it does mean that there is no PI policy and no CI policy when we
move into the final /8 phase. This was discussed at length during the
process discussing the final /8 policy.
Now, what policy reserves 203.119.0.0/16 for CI? APNIC has chosen to use
203.119.0.0/16 for CI (for their and Internet operational reasons), but
there is no policy mandating that this address block cannot be used for
anything else.
So this is all very simple in my view - once APNIC has no other IPv4
address space left to distribute, the final /8 policy comes into force.
