V4 Deplete V6 Adopt
- 1. IPv4 DepletionIPv6 Adoption 3 February 2011 0 /8s Remaining
- 3. First developed for the original Internet (ARPANET) in spring 1978
- 4. Deployed globally with growth of the Internet
- 5. Total of 4 billion IP addresses available
- 6. Well entrenched and used by every ISP and hosting company to connect customers to the Internet
- 7. Allocated based on documented need
- 8. Internet Protocol version 6 (IPv6)
- 9. Design started in 1993 when IETF forecasts showed IPv4 depletion between 2010 and 2017
- 10. Completed, tested, and available for production since 1999
- 11. Total of 340,282,366,920,938,463,463,374,607,431,768,211,456 IP addresses available
- 13. IPv4 Address Space Utilization *as of 3 February 2011 4
- 14. Available IPv4 Space in /8s 5
- 15. IPv4 Depletion Situation Report Each RIR received its last /8 from IANA on 3 February 2011. The IANA free pool of IPv4 addresses has reached 0%. While each RIR currently has IPv4 addresses to allocate, it is impossible to predict when each RIR will run out. ARIN publishes an inventory of available IPv4 addresses, updated daily, at www.arin.net. 6
- 16. IPv4 & IPv6 - The Bottom Line We’re running out of IPv4 address space. IPv6 must be adopted for continued Internet growth. IPv6 is not backwards compatible with IPv4. We must maintain IPv4 and IPv6 simultaneously for many years. IPv6 deployment has begun. 7
- 17. RIRs have been allocatingIPv6 address space since 1999. Thousands of organizations havereceived an IPv6 allocation to date. ARIN has IPv6 distribution policies for service providers, community networks, and end-user organizations. 8 IPv6 Deployment has begun
- 18. IPv4 & IPv6 Coexistence Today, the Internet is predominantly based on IPv4. For the foreseeable future, the Internet must run both IP versions (IPv4 & IPv6) at the same time. (When done on a single device, this is called the “dual-stack” approach.) Deployment is already underway. Today, there are organizations attempting to reach your mail, web, and application servers via IPv6... 9
- 20. Internet Service Providers?
- 21. Internet Content Providers?
- 25. Call to Action Your customers want access to the entire Internet, and this means IPv4 and IPv6 websites. Offering full access requires running IPv4/IPv6 transition services and is a significant engineering project. Multiple transition technologies are available, and each provider needs to make its own architectural decisions. 11
- 26. Call to Action Plan out how to connect businesses via IPv6-only and IPv4/IPv6 in addition to IPv4-only. Businesses are beginning to ask for IPv6 over their existing Internet connections and for their co-located servers. Communicate with your peers and vendors about IPv6, and confirm their timelines for production IPv6 services. 12
- 27. Call to Action Content must be reachable to newer Internet customers. Content served only via IPv4 will be accessed by IPv6 customers via transition solutions run by access providers. Plan on serving content via IPv6 in addition to IPv4 as soon as possible. 13
- 28. Call to Action Mail, web, and application servers must be reachable via IPv6 in addition to IPv4. Open a dialogue with your Internet Service Provider about providing IPv6 services. Each organization must decide on timelines, and investment level will vary. 14
- 29. Call to Action There was probably limited demand for IPv6 in the past. Demand for IPv6 support will become mandatory very, very quickly. Introduce IPv6 support into your product cycle as soon as possible. 15
- 30. Coordinate with industry to support and promote awareness and educational activities. Adopt regulatory and economic incentives to encourage IPv6 adoption. Require IPv6 compatibility in procurement procedures. Officially adopt IPv6 within your government agencies. 16 Call to Action
- 31. IPv6 Adoption Needs IPv6 address space IPv6 connectivity (native or tunneled) Operating systems, software, and network management tool upgrades Router, firewall, and other hardware upgrades IT staff and customer service training 17

- This presentation describes the impending depletion of Internet Protocol version 4 (IPv4) and the importance of adopting the next version of the Internet Protocol, Internet Protocol version 6 (IPv6). This issue impacts everyone and must be understood and acted upon to ensure the continued growth and operation of the Internet.
- IPv6 provides a much larger pool of IP addresses. IPv6 is not backwards compatible with IPv4. The much larger IPv6 numbering system is meant to one day completely replace IPv4, but this will take many years. In the meantime, much of the Internet will run IPv4 and IPv6 simultaneously. This is necessary to ensure all users, regardless of the protocol version they are using, will be able to interact with all content on the Internet.

This is necessary to ensure all users, regardless of the protocol version they are using, will be able to interact with all content on the Internet.
- To ensure your web and mail servers are able to communicate with all users, regardless of the protocol version they are using, you must make them available over both IPv4 and IPv6. As the IPv4 free pool is depleted, many service providers will begin adding users to the Internet using IPv6. The already-deployed IPv4 base will remain with us for many years, however. It is important to support both versions of the protocol for many years to come.
- Organizations will need IPv6 address space to dual-stack their services. IPv6 address space is available either directly from an RIR or from an Internet Service Provider. To connect to the IPv6 portions of the Internet, you will need to get connectivity natively from your service provider, or through another organization that provides IPv6 tunneling services. It is important going forward to make IPv6 support a consideration when making any new purchases of network equipment and software. To upgrade your services to support both IPv4 and IPv6 you may need to acquire new equipment or update what you currently have with firmware updates. It is important your IT staff be trained to support IPv6. Many will be able to self-train using already available resources, however formal training is available through training vendors if needed.
- ARIN hosts a resource center devoted to IPv4 and IPv6 issues. Visit IPv4 / IPv6: The Bottom Line at https://www.arin.net/knowledge/v4-v6.html for information including statistics sheets, this slide deck, the 2007 ARIN Board Resolution on IPv4 depletion, the letter ARIN sent to corporate CEOs advising them of the IPv4 depletion issue, how to find ARIN on social media networks including Facebook, Twitter, and YouTube, and other resources.ARIN’s www.getipv6.info site is a wiki to facilitate IPv6 adoption discussions. Anyone is welcome to use the wiki. Many people have shared their IPv6 adoption information on the site and there are useful links and other resources available. Please share your adoption experiences by posting to the wiki.In May of 2007 the ARIN Board of Trustees issued a resolution advising the Internet community on IPv6 adoption. The advisory recognizes the imminent depletion of IPv4 resources and advises organizations to adopt IPv6. In April of 2009 the ARIN Board of Trustees directed ARIN staff to send a letter via certified mail to the CEO of every organization currently holding an IPv4 registration in the ARIN region. The purpose of this effort is to raise executive awareness of the depletion of IPv4 resources and to encourage the active adoption of IPv6. The letter also serves as notification that, in response to the approaching depletion of the IPv4 free address pool, the Board has directed ARIN staff to take additional steps to ensure the legitimacy of all IPv4 address space requests. ARIN now requires that all applications for IPv4 address space include an attestation of accuracy from an officer of the organization.
