IPv6 has got enough rope (features) that you can hang yourself in most of the same ways as ipv4. If anything, these 'enhanced' versions of ipv4 features give you new and exquisitely delicious ways of screwing yourself. eg: You can do the same kinds of damage with source routing in both ipv4 and ipv6 when it is enabled. OS developers can make the same mistakes parsing options in both. And so on. (Who remembers the ipv4 'ping of death' in the early 90's? you could send a packet with a zero-length option to random hosts and instantly kill them) -- Peter Wemm - peter@wemm.org; peter@FreeBSD.org; peter@yahoo-inc.com "All of this is for nothing if we don't go to the stars" - JMS/B5 "If Java had true garbage collection, most programs would delete themselves upon execution." -- Robert Sewell
