Is this Plan Feasible?
Deploy IPv6 across some 2 billion users, with more than a billion end hosts, hundreds of millions of routers, firewalls and middleware units, audit billions of lines of configuration codes and filters, and audit hundreds of millions of ancillary support systems - all within the next 120 days.

The Economics of Technology Evolution
Why are we facing IPv4 address exhaustion?Why have we left it so long to engage with the transition to IPv6?What can we learn from economics?
![Page 12: An Economic Perspective on IPv6 Transition Geoff Huston APNIC](https://reader036.vdocument.in/reader036/viewer/2022062618/55148c9e550346f06e8b4fce/html5/thumbnails/12.jpg)
Lessons from the Past
If this transition to IPv6 is proving challenging, then how did we ever get the IPv4 Internet up and running in the first place?
Can demand and supply models of markets show us what happened in the switch from telephone networks to IP networks?

IPv4 Deployment
IP networks exposed new market opportunities in a market that was actively shedding many regulatory constraints
– presence of agile high-risk entrepreneur capital willing to exploit short term market opportunities exposed through arbitrage of circuits
– volume-based suppliers initially unable to redeploy capital and process to meet new demand
• unable to cannibalize existing markets• unwilling to make high risk investments

What about IPv6 Transition?
Will the same technology, cost and regulatory factors that drove the deployment of the IPv4 Internet also drive this industry through the transition from IPv4 to IPv6?

Impasse?
• To get to an IPv6 network we need to operate a dual stack hybrid model for a transitional period
• But the higher cost and lower perception of utility of imply that there is no ‘natural’ market driver to propel either producers or consumers into a dual stack transition service
![Page 31: An Economic Perspective on IPv6 Transition Geoff Huston APNIC](https://reader036.vdocument.in/reader036/viewer/2022062618/55148c9e550346f06e8b4fce/html5/thumbnails/31.jpg)
Something has to break!
Demand appears to be constantly increasing, not slowing
And our stocks of IPv4 addresses are finite, and addresses are about to jump in price
So how might this be resolved?

Impasse 2.0
• It’s the new users and new uses of the Internet that are are the immediate beneficiaries of an IPv6 network, and the immediate victims of continued stasis in IPv4
• But the incremental economic value of these additional users and uses does not appear to outweigh the costs of transition in the installed base
• And the larger the installed base of IPv4, the greater the economic resistance to change
![Page 36: An Economic Perspective on IPv6 Transition Geoff Huston APNIC](https://reader036.vdocument.in/reader036/viewer/2022062618/55148c9e550346f06e8b4fce/html5/thumbnails/36.jpg)
“Tipping Points”
If the value of the new users and uses is disproportionately high, compared to the installed base, the actions of this small subset of users can influence the actions of the installed baseSuch situations can lead to a “tipping point” where adoption of a new technology by a small set of influencers can direct a far larger market
![Page 37: An Economic Perspective on IPv6 Transition Geoff Huston APNIC](https://reader036.vdocument.in/reader036/viewer/2022062618/55148c9e550346f06e8b4fce/html5/thumbnails/37.jpg)
The Mobile Internet
The mobile “smartphone” market retailed 300M units in 2010 (Gartner)
This market sector:earns the highest margin per useris growing at the fastest ratewill be one of the first to feel the impacts of address scarcityshould be able to provide clear market impetus in the transition to IPv6
![Page 38: An Economic Perspective on IPv6 Transition Geoff Huston APNIC](https://reader036.vdocument.in/reader036/viewer/2022062618/55148c9e550346f06e8b4fce/html5/thumbnails/38.jpg)
But…
• Public or Private?Will the mobile market continue to open their users to the entire Internet or head back into private walled gardens and lock up users and content?
• Google’s Android model• Apple’s App Store and the iPhone model
![Page 39: An Economic Perspective on IPv6 Transition Geoff Huston APNIC](https://reader036.vdocument.in/reader036/viewer/2022062618/55148c9e550346f06e8b4fce/html5/thumbnails/39.jpg)
Much of the answer to the question: “where to now?”
for the Internet depends on the direction being taken by the mobile sector in response to address scarcity.
So why is this not just a simple case of “just use IPv6 and lets move on!” ?
Why are we wedged on IPv6?
![Page 40: An Economic Perspective on IPv6 Transition Geoff Huston APNIC](https://reader036.vdocument.in/reader036/viewer/2022062618/55148c9e550346f06e8b4fce/html5/thumbnails/40.jpg)
Why are we wedged on IPv6?
Cost and Benefit are not aligned:
Those folk who have been historical "losers" with the open Internet - the carriers - are now being asked to make the bulk of the investment in IPv6 access infrastructure
They are understandably reluctant to make further investments that in the end just worsen their long term revenue prospects
![Page 41: An Economic Perspective on IPv6 Transition Geoff Huston APNIC](https://reader036.vdocument.in/reader036/viewer/2022062618/55148c9e550346f06e8b4fce/html5/thumbnails/41.jpg)
Cost and Benefit are not aligned:
Those folk who have benefitted from an open network in the past are increasingly ambivalent about open networks and IPv6 into the future
They are now part of the set of entrenched incumbents, with market positions to protect
Why are we wedged on IPv6?
![Page 42: An Economic Perspective on IPv6 Transition Geoff Huston APNIC](https://reader036.vdocument.in/reader036/viewer/2022062618/55148c9e550346f06e8b4fce/html5/thumbnails/42.jpg)
Why are we wedged on IPv6?
Cost and Benefit are not aligned:
Those folk with the most to gain in the longer term from continuation of an open network - consumers - do not necessarily act from day to day in their own long term interests
i.e. consumers are unwilling to fund this transition through higher prices for Internet services
![Page 43: An Economic Perspective on IPv6 Transition Geoff Huston APNIC](https://reader036.vdocument.in/reader036/viewer/2022062618/55148c9e550346f06e8b4fce/html5/thumbnails/43.jpg)
Is the Open Pendulum swinging back?
Continued delay by incumbents to embrace IPv6 allows further consolidation, and increased ability by incumbents to define (and limit) the parameters of future competition.
What is at risk here is the future of a truly open public network infrastructure
![Page 44: An Economic Perspective on IPv6 Transition Geoff Huston APNIC](https://reader036.vdocument.in/reader036/viewer/2022062618/55148c9e550346f06e8b4fce/html5/thumbnails/44.jpg)
If we really want to keep a truly Open Internet...
Then we need to alter the market environment to favor the rapid adoption of IPv6!
Working out how to do this on the fly is proving to be extremely challenging
![Page 45: An Economic Perspective on IPv6 Transition Geoff Huston APNIC](https://reader036.vdocument.in/reader036/viewer/2022062618/55148c9e550346f06e8b4fce/html5/thumbnails/45.jpg)
