Are we facing IPv4 depletionDid we run out of IPv4 addresses?

The central pool of available IPv4 (Internet Protocol Version 4) addresses by the Internet Assigned Numbers Authority (IANA) is lowering or depleting. When you look at the IPv4 exhaustion details, the majority of the 4.29 billion IP addresses have already been assigned or reserved to corporations or institutions. We are in the technology age where just about everything we do, we rely on the internet. Just about everything we take part in, needs an IP address (Internet Protocol Address). The internet has grown and surpassed a population of 6 billion internet users of not only one, but multiple internet capable devices in our everyday life (IPV4 DEPLETION TODAY).

Will IPv4 ever go away?

The good news is, just because the free IPv4 addresses are depleted, that does not mean all addresses have run out. IPv4 addresses were bought by many institutions to be used for a rainy day. However, since those IPs remained unused for a long time, the same companies are now selling IP addresses (IPV4 DEPLETION TODAY).


Facts to Know before Entering the IPv4 Marketplace


Because corporations are selling back or trading them, this frees up many for institutions not interested in switching to IPv6.

Three ways that can free up addresses on the waiting list:

  • Redistribution of Internet Assigned Numbers Authority (IANA)– Requires IANA to allocate equal shares to each of the five RIRs of total recovered addresses twice a year to fill the IPV4 waiting list. Recovered space is posted
  • IPv4 Blocks Returned – Organizations return unused IPv4 blocks. The returned space is then available to redistribute to the waiting list.
  • Revoked IPv4 Blocks – When organizations do not comply with terms and conditions, it often results in a revoked IPv4 block. The block is then back on the available waiting list.IPv4 Blocks and CIDR Netting

Why are companies not switching to IPv6?

Many years ago, IPv4 depletion prediction was sounded, and now companies are slowly adapting to the idea. 

The progress is slow to switch over to the new protocol because:

  • For the most part it is costly
  • Many routers and servers do not support IPv6 as of yet
  • IPv4 dominates most of the Internet traffic
  • IPv6 is not compatible with many firewalls, routers, switches and would require upgrades to many organizations IP infrastructure.

American Registry for Internet Numbers (ARIN) has a waiting list that organizations can get on to wait for IPv4 addresses to become available. However, because many other agencies are selling off their IPv4 addresses, buying addresses on the open market is an option (IPV4 DEPLETION TODAY).

IPv4 Block broker matching services:

Regardless of whether you need to release or buy IPv4 block, ARIN has a Specified Transfer List Service (STLS). This service matches pre-approved organizations that want to release their address space to pre-approved organizations wishing to receive or buy addresses. 

To have complete solutions for IP address transfer and verification, one needs Matching Services. 

Broker services can also register through STLS as a facilitator to complete transfers.

Brokers of IPv4 are specialist who can connect buyers with sellers who have ready address space. 

Most brokers have access to an ample supply of IPv4 addresses that gives organizations a variety of choices to extend and support their existing network and to gear up to migration and deployment to IPv6.

While it is possible to buy IPv4 addresses alone, finding, buying, and closing transactions can be complex. Brokers generally have the knowledge and are current with the nuances and governance policies that affect market transactions.

Buying and selling IPv4 addresses are a lot like an acquisition or merger, and the terms and conditions may be a bit confusing for someone not experienced, hiring a broker is often the best course of action.

If the depletion of IPv4 has you a bit worried, an IPv4 broker can help in your transition to help you feel confident that the transaction will be a smooth success.
