Regional Internet Registries (RIRs) have been\u00a0running out<\/a>\u00a0of IPv4 addresses to give to organizations that operate in their respective geographies.\u00a0 Early on the run-out was difficult to predict because policies were still in flux.\u00a0 However, in recent years, with the soft-landing policies each RIR adopted the recent address run-out has been slow but steady.<\/p>\n

There have been many address exhaustion predictive models, but the one that has been kept current and seems to be the most accurate is the one created by\u00a0Geoff Huston<\/a>.\u00a0 Following is his recent address exhaustion prediction graph.<\/p>\n

 <\/p>\n

IANA<\/h2>\n

The Internet Assigned Number Authority (IANA<\/a>) allocated addresses to the RIRs operating around the world.\u00a0 On February 3, 2011 they allocated the last of the \/8 blocks to the RIRs.\u00a0 From that point on, it was up to the RIRs to manage their finite resource.<\/p>\n

APNIC IPv4 Address Exhaustion<\/h2>\n

The APNIC RIR reached their final \/8 equivalent amount of available IPv4 addresses on April 15, 2011.\u00a0 At that point they moved from\u00a0Stage 2<\/a>\u00a0exhaustion to\u00a0Stage 3<\/a>.<\/p>\n

RIPE NCC IPv4 Address Exhaustion<\/h2>\n

RIPE NCC<\/a>\u00a0reached their final \/8 equivalent on\u00a0September 14, 2012<\/a>.\u00a0 Since then, like APNIC, they have only been allocating \/22 blocks to Local Internet Registries (LIRs) on an emergency basis.<\/p>\n

LACNIC IPv4 Address Exhaustion<\/h2>\n

The LACNIC has also been managing their final addresses.\u00a0 However, their economies are growing and more members of their communities are getting connected to the Internet driving addressing pressure.\u00a0 This\u00a0page<\/a>\u00a0states the LACNIC IPv4 address\u00a0depletion<\/a>\u00a0phases.<\/p>\n

AFRINIC IPv4 Address Exhaustion<\/h2>\n

The Africa region has been increasing their Internet connectivity over the years.\u00a0 More and more people are getting connected to the Internet and that means that more people in that region need IPv4 addresses.\u00a0 However, the\u00a0AFRINIC<\/a>\u00a0RIR has a slower address consumption rate of other RIRs and they are not likely to run out for many years.<\/p>\n

Stages of IPv4 Address Exhaustion<\/h2>\n

As each of these RIRs has been reaching their final IPv4 blocks of addresses, they have been using\u00a0soft-landing policies<\/a>\u00a0to gracefully run-out.\u00a0 Each RIR has had their own policies and their own definitions for how they are managing the final blocks of their address space.\u00a0 Now, these RIRs are going to have to aggressively conserve their final address blocks.<\/p>\n

ARIN IPv4 Address Exhaustion<\/h2>\n

Today, the American Registry for Internet Numbers (ARIN<\/span><\/a>) has announced that they have reached their final \/8 equivalent amount of IPv4 addresses.\u00a0 At this point, ARIN will now move into Phase 4 of their IPv4\u00a0countdown<\/span><\/a>\u00a0plan.\u00a0 Now, IPv4 addresses are only allocated with increased scrutiny and it will be extremely difficult to justify that your organization needs a large block of IPv4 addresses.\u00a0 Based on ARIN\u2019s Number Resource Policy Manual (NRPM), organizations may only qualify to receive smaller blocks.\u00a0 As people have said before, if it is so difficult to get your address request granted, we have effectively run out of addresses.\u00a0 This is a difficult situation because most organizations have no plans to stop using IPv4 in the next 20 years.<\/p>\n

Address Transfer Market<\/h2>\n

If your RIR has reached exhaustion and you are not a LIR or service provider and you are an enterprise organization, then the only way for you to get IPv4 addresses in the future is to buy them.\u00a0 Your organization will need to work out an arrangement with an organization that has IPv4 addresses for sale.\u00a0 You can negotiate whatever price the current market dictates.\u00a0 Then you can perform an\u00a0address transfer<\/a>\u00a0with your RIR to keep the records updated.\u00a0 If you are interested in how this works in the ARIN region, here is a link to their transfer policies.<\/p>\n

The concern here is that over time the price of IPv4 addresses will increase as they become increasingly scarce.\u00a0 Currently, the price of an IPv4 address is between $15 and $30, however, these prices can quickly reach $100 or more per address.\u00a0 A \/24 could end up costing your organization $25,000.<\/p>\n

Is It Too Late for IPv6 Planning?<\/h2>\n

The Internet community has been anticipating that the exhaustion of IPv4 addresses would help drive interest in IPv6.\u00a0 All organizations need to consider if they have enough IPv4 addresses to sustain their businesses indefinitely.<\/p>\n

It is human nature to put off the inevitable until the last minute.\u00a0 For example, people seem to like driving in the fast-lane of the freeway and then just start planning to exit the highway just as they pass their exit.\u00a0 Some people put off buying a new toothbrush until their brush only has a few bristles remaining.<\/p>\n

Now it is beyond the point where organizations should start to plan for IPv6.\u00a0 In other words, the airplane has run out of gas and the engines are stopped so you had better start to think about packing your parachute.\u00a0 The truth is, your organization should have been planning for IPv6 years ago.\u00a0 If your organization just started to contemplate IPv6, you will likely be struggling for the next couple of years to get IPv6 implemented.<\/p>\n

If your organization has procrastinated and hasn\u2019t started planning for IPv6, there is no time like the present.\u00a0 You are encouraged to use an IPv6\u00a0address planning<\/a>\u00a0utility and determine how much IPv6 address space you may need.\u00a0 Then hurry up and make your request for IPv6 addresses from your RIR.\u00a0 At that point, you can start to implement IPv6 at your\u00a0Internet perimeter<\/a>\u00a0and then start to gradually bring the deployment into your organization.<\/p>\n","protected":false},"excerpt":{"rendered":"
