IPv6 is enabled by default (Vista, Linux, Mac OS/X, ...) •  Your network: Does not run IPv6 •  Your assumption: I’m safe •  Reality You are not safe Attacker sends Router Advertisements Your host configures silently to IPv6 You are now under IPv6 attack •  => Probably time to think about IPv6 in your network 23

Troubleshooting, downtime, expense •  NAT has slowed growth of transparent applications (need ALG’s) INHIBITS GROWTH - scalability issues with TURN, ICE and STUN ADDS TO COST - Problem typically ends up with the applications team •  NAT breaks security (IPSec/Authentication Header etc) •  NAT complicates mergers, double NAT-ing is needed for devices to communicate with each other •  Large scale NAT at the Carrier level (e.g. NAT64/NAT464/NAT444) is NEVER going to be a permanent solution – speed/complexity/cost
