[ih] Why is TUBA assigned IP version 9

[John Day]

There were more than 4.  I can't remember but who was the strange guy 
with the v8?  Vaguely remember he was from Naperville, either Bell 
Labs or Fermilab connection.  It was distinctly an outlier.

But right, 6 was initially skipped and then went back and used it.
