ARIN now has 2 /8s of available space in its inventory and has moved 
into Phase Three of its IPv4 Countdown Plan.

This phase was designated to allow for process refinements identified 
during Phase Two.  Based on successful operational experience, ARIN will 
continue to adhere to the same procedures during Phase Three.

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 three months.
