You can safely say that 72.234.7.0/24 is a 
Class C /sized/ network. 
--------------------------------------

But most don't say that.  They just say it's 
a Class C, which it most assuredly is not.  
I heckle them until they can give the correct 
answer: leading bits are 110 or it's not a 
Class C subnet.
