Roll the lawyer jokes... It's a big and diverse planet out there. In my 40+ years career I've used, implemented and deployed many different networking systems. Most of them are gone now, just IP (v4 and v6) remains. And use is slowly shifting from IPv4 to IPv6 now. > [..] > If you've ever tried to grok the IPv6 spec, your brain will explode... Must have happened to me some 20 years ago then. Probably the reason why I rarely get a head ache :-) Wolfgang
