Actually, I would assume it to be the other way around: if you only communicate with people who are active in the field who are aware of all the new tricks, how are you going to learn about obsolete stuff? About classfulness: I think it's more relevant, even today, than many people like to admit. Why is it that I can type "network 192.0.2.0" in my Cisco BGP config and the box knows what I'm talking about, but "network 192.0.2.0/24" is no good? If it doesn't do anything else, at least IPv6 will get rid of this problem. Iljitsch van Beijnum
