ARIN now has 3 /8s of available space in its inventory and has moved
into Phase Two of its IPv4 Countdown Plan.

There are three key changes that are triggered in this phase.

1. All /16 and larger IPv4 requests will be placed in the IPv4 Review
Team queue, and will be reviewed in the order they were received
according to their timestamp. Because each correspondence will be
processed in sequence, it is possible that response times may exceed the
usual two-day turnaround.

2. Once a request is approved, the requestor will have 60 days to
complete payment and return a signed RSA (if applicable). If payment and
signed RSA have not been received by the 61st day, the ticket will
automatically close, the address space will be released back into the
available IPv4 pool, and a new request will need to be submitted.

NOTE: This change to the approval window from 90 days to 60 days will
apply to all IPv4 requests, but not to IPv6 and ASN requests.

3. The hold time for all returned, reclaimed and revoked IPv4 resources
will be reduced from six to three months.

Phase 2 will provide ARIN staff operational experience using the team
review approach to ensure that these processes and procedures are
effective for managing the distribution of the last of its IPv4 address
