Not least of them is that IPv6 will include sophisticated encryption capabilities as part of protocols. Such security isn't built in to Internet now, one of reasons why electronic commerce has yet to take off, said Mark McFadden, communications dir. That feature will make it harder for law enforcement to gain access to information, he said. Anyone who anticipates using tools to guarantee that everything will be traceable is not going to have a successful outcome. Technically, such project could be accomplished, Cerf said, but having administrative infrastructure to administer it is quite different issue.
Law enforcement has some time to work with Internet community.
McFadden said IPv6 isn't scheduled to be implemented at consumer level for at least 5 years, possibly as much as 10. There was some urgency when it appeared that reservoir of Internet addresses would dry up, but with progress being made to protect addresses as scarce resource there's less pressure for new set of protocols, he said.
