“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

Mean while … IPv4 run-out is very real

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%.
