About a week ago, of the 118784 networks allocated or assigned by the
five Regional Internet Registries, 600 had a '255' in the second or
third octet.  5 of those 600 (128.255.0.0 being UofIowa, 170.255.0.0.
192.12.255.0, 192.51.255.0 and 192.66.255.0) were assigned in the late
1980s.  I think someone might have noticed by now.

About a week ago, there were 11619 IPv6 networks - and for perspective
there were 11675 IPv4 networks at the end of 1991.

Nearly all computer users wouldn't even recognize an IP address of
either version 4 _or_ 6.
