Tag This: IPv4 Runout

by

With less than 45K IPv4 addresses remaining in the ARIN inventory, IPv4 depletion here at ARIN is only weeks away. We thought it’d be fun to get your ideas about the tag line we should use when ARIN hits IPv4 runout. Maybe we’ll even take you up on a few of these. Here’s what you came up with so far

Waiting List for Unmet IPv4 Requests

by

As described in an announcement on 1 July 2015, ARIN has activated the Unmet Requests Policy. Organizations are currently electing to accept block sizes smaller than those for which they qualified or are electing to be placed on the Waiting List for Unmet Requests. So far, 21 organizations have elected to be placed on the waiting list and ARIN expects there to be over 100 soon.
