[6bone] pTLA for Teredo testing - review closes 7 August 2002

I'd like to better understand:

- what is being requested exactly. Will any prefix of length /32 or
  shorter work? (this is a purely technical question)

- What will this allocation be used for? experimentation and testing?
  Note that 6bone addresses are intended for experimentation, and must
  be returned at some point in the future. Thus, if this allocation
  will in practice be used in some sort of permanent sense (e.g.,
  hardcoded in to-be-shipped products), using a pTLA seems
  inappropriate.
