History of the Internet Protocol• Internet Protocol version 4 (IPv4)
– Developed for the original Internet (ARPANET) in 1978– 4 billion addresses– Deployed globally & well entrenched – Allocated based on documented need
• Internet Protocol version 6 (IPv6)– Design began in 1993 when IETF forecasts showed IPv4
depletion between 2010 and 2017– 340 undecillion addresses– Completed, tested, and available since 1999– Used and managed similar to IPv4

IPv4 Depletion Situation ReportEach RIR received its last /8 from IANA on 3 February 2011
3
The IANA free pool of IPv4 addresses reached 0%

Why so little IPv4 left?
• The community-developed policies that manage how IPv4 is allocated and assigned did:– Extend the life of the IPv4 – BUT…IPv4 depletion is unavoidable
• Not enough addresses to meet growing need of the global Internet

ARIN’s IPv4 Countdown Plan• Process for final IPv4 requests– Divided into 4 phases– Length of each could vary• Global policy to return space to IANA• Faster depletion due to:
– Large requests– Policy changes 2.14

How can you get started?• Dual-Stack your networks
– IPv6 not backwards compatible with IPv4– Both will run simultaneously for years
• Servers must be reachable via both IPv4 and IPv6– Mail– Web– Applications
• Do you operate a website? • Ensure content will be available to all customers• Even new Internet users with an IPv6-only
address

How can you prepare?• Talk to your ISP about IPv6 services
– You want access to the entire Internet
• ISPs must connect customers via IPv4-only, IPv4/IPv6, & Via IPv6-only
• Must plan for IPv4/IPv6 transition services
– Many transition technologies available
• Research options
• Make architectural decisions

What else can you do?
14
• Audit your equipment and software– Are your devices and applications IPv6
ready?
• Encourage vendors to support IPv6– If not already, when will IPv6 support be
part of their product cycle?
• Get training for your staff– Free resources available
![Page 15: IPv6: Paving the way for next generation networks Tuesday, 16 July 2013 Nate Davis](https://reader035.vdocuments.net/reader035/viewer/2022070415/56814fbb550346895dbd74a0/html5/thumbnails/15.jpg)
What Can Governments Do?• Government and the Internet
community need to coordinate to support and promote
– IPv6 awareness
– IPv6 education
• Governments should consider:
– Regulatory and economic incentives to encourage IPv6 adoption
– Required IPv6 compatibility in procurement procedures
– Official IPv6 deployment within agencies

Your IPv6 Check List
IPv6 address space
IPv6 connectivity (native or tunneled)
Operating systems, software, and network management tool upgrades
Router, firewall, and other hardware upgrades
