It's good to have at least a passing understanding of 
the old terminology simply because documentation for 
newer stuff likes to reference it...

Plus it's fun (and informative about a netgeek's skill) 
when they call, say, 72.234.7.0/24 a Class C and you 
can say no it's not.  Then you see if they can say why.  
If they can't, well...ummm... I really mess with them 
after that.  It helps pass the work day. >;-)
