==IPv4 Exhaustion==

On February 2011,the Number Resource Organization ([[NRO]]) announced that the free pool of available IPv4 addresses has been fully depleted. on January 31, IANA allocated two blocks of IPv4 address space to APNIC. The action triggered a global policy to allocate the remaining IANA pool equally between the five Regional Internet Registries ([[RIR]]).IANA assigns IPv4 addresses to the RIRs in blocks that equate to 1/256th of the entire IPv4 address space. Each block is referred to as a “/8″ or “slash-8″. <ref>[http://www.nro.net/news/ipv4-free-pool-depleted www.nro.net]</ref> In 2009, [[ICANN]] ratified a global policy agreed upon by the RIRs stipulating that when the IANA IPv4 free pool reached five remaining /8 blocks, It will be simultaneously and equally distributed to the five RIRs.

In February, 2011, the [[NRO|Number Resource Organization]] announced that the free pool of available IPv4 addresses had been fully depleted. On January 31, IANA had allocated two blocks of IPv4 address space to [[APNIC]]. The action triggered a global policy to allocate the remaining IANA pool equally between the five [[RIR|Regional Internet Registries]]. IANA generally assigns IPv4 addresses to the RIRs in blocks that equate to 1/256th of the entire IPv4 address space. Each block is referred to as a “/8″ or “slash-8″. <ref>[http://www.nro.net/news/ipv4-free-pool-depleted www.nro.net]</ref> In 2009, [[ICANN]] ratified a global policy agreed upon by the RIRs stipulating that when the IANA IPv4 free pool reached five remaining /8 blocks, It will be simultaneously and equally distributed to the five RIRs.

The last five blocks of IPv4 addresses were allocated to the five RIRs during a ceremony and meeting of the RIRs which was held in Miami, Florida. According to ICANN, the allocation of the final IPv4 addresses is analogous to the last crates of a product leaving a manufacturing warehouse and going to the regional stores or distributions centers, where they can still be distributed to the public. Once they are gone, the supply is exhausted. In this case, the RIRs will distribute the last IPv4 addresses to [[ISP|Internet Service Providers]], universities, governments, telecommunications companies and other enterprises. [[Raul Echeberría]], Chairman of the NRO emphasized, "It’s only a matter of time before the RIRs and Internet Service Providers (ISPs) must start denying requests for IPv4 address space". He also pointed out that, "Deploying [[IPv6]] is now a requirement, not an option”.<ref>[http://www.icann.org/en/news/releases/release-03feb11-en.pdf www.icann.org]</ref>
