North American IPv6 Summit

Last week, Denver hosted the 2012 North American IPv6 Summit.

The keynote by John Curran of ARIN kicked things off nicely.  My favorite points were:

  1.  A few years ago, NAT was sounding the death knell for IPv6 adoption.
  2. Today, media providers are hindered by NAT. (Think tracking and targeting...)  Follow the money people - IPv6 is gaining support.

Other interesting tidbits overheard:

  1. Enable a client for IPv6 and see content come in that way as much as 10% of the time.
  2. Enable a web server for IPv6 and only get <1% traffic over it.
  3. Over 30% of DNS domains are IPv6-enabled largely due to efforts of Godaddy and other leading registrars.

I learned from Oracle's Paul Zawacky that 'dual stack' is becoming the transition method of choice.  Owen Delong from Hurricane Electric advised to stick with a /64 per VLAN and stay away from "IPv4 thinking" when considering alternate subnet masks.  Finally, NAT64 is a very interesting method for moving all hosts to a pure-IPv6 environment and maintaining v4 Internet access.

@scotthogg organized and summarized the event quite nicely.  Thanks!
