ARIN has issued its initial response to ACSP Suggestion 2015.1. The 
suggestion and response text are provided below. This suggestion is now 
closed and is available at:



Communications and Member Services
American Registry for Internet Numbers (ARIN)

Suggestion: *

Description: Submitter seeks clarification of ARIN's countdown phases 
(https://www.arin.net/resources/request/ipv4_countdown.html) and 
intended operational practices after the ARIN general free pool becomes 
empty, implying that we are substantially in a transfer-only ecosystem.

Does ARIN remain in Phase 4 of the IPv4 Countdown Plan, and if not, what 
is Phase 5?

Value to Community: There may be policy tweaks or further ACSP 
suggestions warranted based on ARIN's operational plans.


Going forward, including after the depletion of ARIN's IPv4 free pool, 
we intend to remain in Phase 4 for requests submitted against ARIN's 
IPv4 free pool. We anticipate requests for IPv4 address space from the 
ARIN free pool to continue following depletion with customers electing 
to be placed on the waiting list for unment requests, as specified in 
paragraph 4.1.8 of the ARIN Number Resource Policy Manual. We do not 
currently plan to create a 5th phase for IPv4 depletion procedures. We 
have recently published information on the ARIN public website to 
increase clarity on this matter.

AS number requests, IPv6 requests, and transfer requests of all types 
will be processed as normal, and not reviewed in accordance with the 
phased countdown procedures.

Thank you again for using the ARIN Consultation and Suggestion Process. 
This request for clarification will now be closed. If you wish to submit 
a related suggestion based on this response, please submit a new suggestion.
