Actually, the PDN /8 was allocated for integrating X.25 networks into  
the Internet.  Individual /32s were assigned to X.25 endpoints run by  
different companies, so representing 14/8 as "a whole /8 for an  
organization of less than 20 people" is not accurate.

And besides, Leo Vegoda has been very active in recovering the /32s  
so we can return 14/8 to the free pool.  There used to be over 200  
assignments in that /8.

There are lots of better examples in the "legacy /8" space, however  
I'm not sure "historical reasons" is a good rationale for current  
policy in an entirely different address space.

Because root name server addresses must be encoded into  
configurations of all caching servers on the Internet, I believe that  
they are very special and should be treated specially.
