+ - ARIN runs out of IPv4 addresses->

colinneagle (2544914) writes "After IANA allocated the final IPv4 addresses to the five Regional Internet Registries (RIRs) on February 3, 2011, the RIRs have been running out of IPv4 addresses over the past three years. APNIC ran out on April 15, 2011; RIPE NCC ran out on September 14, 2012; and now ARIN has run out on April 23, 2014.

After today’s announcement by ARIN, they have now entered Phase 4 of their IPv4 exhaustion plan. Their Number Resource Policy Manual (NRPM) defines the process that organizations can request IPv4 addresses. At this moment, IPv4 addresses will only be allocated on an emergency basis. This means that an ISP can make one final request for a /22, but after that they will not get any more address space.

This may be concerning for many organizations that intend to continue using IPv4 for decades to come. There are probably no organizations in the ARIN territories that are actively planning to stop using IPv4 at some point in the future. Organizations that are desperate for addresses can purchase them through the address transfer marketplace. ARIN permits address transfers to take place, but you must follow their rules as part of the address transfer process. Over time, the price of an IPv4 address will increase from $15 to $30 today to well over $100 in the not-so-distant future."
