A guest speaker at this year's Defcon network security conference criticized the security of IPv6 in a big way. One potential trouble spot with the protocol is its handling of ICMP (better known as ping) messages. Beyond that, some folks seem to be afraid that IPv6 hasn't been well tested enough yet to find all the major security exploits. After numerous years of IPv6 development and it being touted as the imminent replacement for IPv4, it's hard to believe sufficient testing of the new protocol hasn't been completed by now.

I have been hearing that IPv6 is going to be implemented for the last 10 years.
When will I get to see the 6 octets instead of 4?
