“A deadlock, stalemate, impasse; a roughly equal (frequently unsatisfactory) outcome to a conflict in which there is no clear winner or loser,”
Where is the content? Too much pain &
no gain
Where is the network?
Do I pay less ? Any new
applications?
NAT’s are good. RFC1918 gives me security, and IPv4 address runout is my ISP’s problem.
The network is not ready, users don’t care and I don’t
want to risk a poor end-user experience today for potential gains tomorrow

The world will run out of IPv4 addresses .
By 2016 there will be 7.5 billion people...
...and 19 billion fixed and mobile-connected devices (up from 10 billion in 2011) .
M o b i l e d e v i c e s a r e growing faster than the mobile subscribers that use them. 2.5 devices / capita in 2016 up from 1.5 in 2010
Globally 8 billion -40% of all fixed and mobile networked devices- will be IPv6-capable in 2016, up from 1 billion or 10% in 2011, a CAGR of 49%.

- CGN44 Capex and Opex is growing driven by Subcribers growth, AND application complexity (session per user)
- CGN44 Cost is capped as Content switches to IPv6. - 6rd cost does not increase much as a function of # IPv6 users, AND Application complexity is transparent

• ~80 % of Internet Core transit (top 5% AS’s) is IPv6 enabled
• > 35% of global Internet content/Web pages are reachable over IPv6
• >1% of Internet users have IPv6 Great disparities across countries
