COMMENT:
----------------------------------------------------------------------

Nice document you have here.  Just two really small comments, neither of
which needs any response, and both of which you can ignore if you
prefer.

An observation: Three times, you say that something is "obvious", and
this can come across as condescending -- and can be frustrating to a
reader for whom it isn't obvious.  I suggest omitting that, so 

- In Section 3.1.1.1, change "Firstly, as it should be obvious from the
algorithm described above" to "Firstly, as shown by the algorithm
described above".

- In Section 3.1.3.2, change "For obvious reasons, the search space for
addresses following" to "The search space for addresses following".

- In Section 3.3, change "Obviously, a number of other network
reconnaissance vectors" to "A number of other network reconnaissance
vectors".

-- Section 3.1.1.1 --

An observation, for which the response is probably "everyone knows this,
so no change is needed," but please think about it for a fleeting
moment:

   1.  The "Universal" bit (bit 6, from left to right) of the address is
       set to 1

Bit 6, starting from 0, or from 1?  The answer (which I can see from the
example) is "starting from 0."

   Firstly, as it should be obvious from the algorithm described above,
   two bytes (bytes 4-5) of the resulting address always have a fixed
   value (0xff, 0xfe)

Bytes 4-5, starting from 0 or from 1?  The answer (which I can see from
the example) is "starting from 1."

The fact that the origins differ makes me think that it'd be nice if that
were made clear.  Please give it a thought, to say that bits are numbered
from left to right starting at 0, and bytes are numbered from left to
right starting at 1.
