DNS globally adopted    Make it scale and do   Need new paradigms
as a network protocol   new things             for security, content
to distribute naming                           distribution, machine
authority to every                             to machine, etc.
organization


   DNS has always prized the ability to evolve;
   Do IPv6 and DNSSEC have useful “DNA” for
              Internet evolution?
Significant Shifts
IP address “explosion” adds to
the volume of data

•  Roughly 4 billion IPv4
  addresses used

•  IPv6 allows 3.4 x 1038 more
  addresses

“Happy eyeballs” – Optimize
the user experience, not
network traffic
