Let us imagine that today is the day after!!!
22 December 2011
And...you need IP address space
What happens??
What will the Internet look like ?
What will you do?
![Page 6: APNIC Depletion of the IPv4 free address pool – IPv6 deployment The day after!! 8 August 2008 Queenstown, New Zealand In conjunction with APAN Cecil Goldstein,](https://reader036.fdocuments.us/reader036/viewer/2022081519/56649ec75503460f94bd3bdb/html5/thumbnails/6.jpg)
Well, that will depend on what happens between now and
22 Dec 2011

• So let us consider then where we are NOW and how we may move to THEN…….

IPv4 address consumption prediction
• Assumptions– Tomorrow is a lot like today– Trends visible in the recent past continue into
the future
• This model assumes that there will be:– no panic– no change in policies– no change in the underlying demand dynamics– no rationing– no withholding or hoarding!
• No really! Ref: IPv4 unallocated address space exhaustion by Geoff Huston, Sept 2007
![Page 21: APNIC Depletion of the IPv4 free address pool – IPv6 deployment The day after!! 8 August 2008 Queenstown, New Zealand In conjunction with APAN Cecil Goldstein,](https://reader036.fdocuments.us/reader036/viewer/2022081519/56649ec75503460f94bd3bdb/html5/thumbnails/21.jpg)
So what will happen after the exhaustion?
• The Internet will not stop but its growth will be impacted
• Who will be impacted?– ISPs
• Sustaining their business models will become more difficult unless you have huge IPv4 address blocks
– End users• Cost of access to the Internet will increase
![Page 22: APNIC Depletion of the IPv4 free address pool – IPv6 deployment The day after!! 8 August 2008 Queenstown, New Zealand In conjunction with APAN Cecil Goldstein,](https://reader036.fdocuments.us/reader036/viewer/2022081519/56649ec75503460f94bd3bdb/html5/thumbnails/22.jpg)
Some possible scenarios
• What will happen after the IPv4 unallocated address space exhaustion?– Persist in IPv4 networks using more NATs– Address markets emerging for IPv4– Routing fragmentation– IPv6 deployment/ transition

Address market ?

IPv6 deployment
Issues and concerns
![Page 25: APNIC Depletion of the IPv4 free address pool – IPv6 deployment The day after!! 8 August 2008 Queenstown, New Zealand In conjunction with APAN Cecil Goldstein,](https://reader036.fdocuments.us/reader036/viewer/2022081519/56649ec75503460f94bd3bdb/html5/thumbnails/25.jpg)
IPv6 current deployment status
• Not many cases of production networks– Not many business cases– Quite a few research and experimental
networks
• Some statistics to review
![Page 26: APNIC Depletion of the IPv4 free address pool – IPv6 deployment The day after!! 8 August 2008 Queenstown, New Zealand In conjunction with APAN Cecil Goldstein,](https://reader036.fdocuments.us/reader036/viewer/2022081519/56649ec75503460f94bd3bdb/html5/thumbnails/26.jpg)

APNIC IPv6 delegations by year
27 As of this date
![Page 28: APNIC Depletion of the IPv4 free address pool – IPv6 deployment The day after!! 8 August 2008 Queenstown, New Zealand In conjunction with APAN Cecil Goldstein,](https://reader036.fdocuments.us/reader036/viewer/2022081519/56649ec75503460f94bd3bdb/html5/thumbnails/28.jpg)
Issues
• Obviously not many production networks deployed– Gap in understanding between front line
network engineers and decision makers• CEOs and CIOs do not seem interested or aware enough to make investments not making tangible profit
• Commercial value
![Page 29: APNIC Depletion of the IPv4 free address pool – IPv6 deployment The day after!! 8 August 2008 Queenstown, New Zealand In conjunction with APAN Cecil Goldstein,](https://reader036.fdocuments.us/reader036/viewer/2022081519/56649ec75503460f94bd3bdb/html5/thumbnails/29.jpg)
Where are we heading?
• We should look to preserve the functionality and integrity of the Internet as a service platform– Functionality of applications– Viability of routing– Capability to sustain continued growth– Integrity of the network infrastructure

But this is not all…..
• We are running into exhaustion of the 16-bit AS Number pool– Estimated exhaustion time: 1200 UTC 1
November 2010– See http://www.potaroo.net/tools/asns
![Page 31: APNIC Depletion of the IPv4 free address pool – IPv6 deployment The day after!! 8 August 2008 Queenstown, New Zealand In conjunction with APAN Cecil Goldstein,](https://reader036.fdocuments.us/reader036/viewer/2022081519/56649ec75503460f94bd3bdb/html5/thumbnails/31.jpg)
RIRs and 32-bit AS Numbers
• From 1 January 2007 the RIRs are allocating 32-bit AS numbers (upon specific request)
• From 1 January 2009 the RIRs will be allocating 32-bit AS numbers by default (leaving some 16-bit AS numbers available upon specific request)

Conclusion
• Plan
• Compare
• Prepare
• Test
• Deploy
IPv6 is not a new product to sell…..it is a means to sustainability
