document and requested various changes. These changes are reflected in
the draft version 14 and the IESG now solicits community input on the

Is that a two-weeks Last Call?
Will the determination of consensus be made only on the basis of this
Last Call?
In Section 3:
"A Service Provider can number the interfaces in question from
legitimately assigned globally unique address space. While this
solution poses the fewest problems, it is impractical because
globally unique IPv4 address space is in short supply."
Unique IPv4 address space is not in short supply in some regions. If
it is globally in short supply, I gather that several regions have
already reached their IPv4 Exhaustion phase. I haven't seen any
announcements about that.
"While the Regional Internet Registries (RIR) have enough address
space to allocate a single /10 to be shared by all Service Providers,
they do not have enough address space to make a unique assignment to
each Service Provider."
The above is incorrect as RIRs are still providing unique IPv4
assignments to service providers that request IPv4 addresses. On
reading this draft, I conclude that as IPv4 addresses are nearly
exhausted, the only option left is to deploy Carrier Grade NAT
instead of requesting IPv4 addresses from a RIR.
For the determination of consensus, I do not support this proposal.
