Folks,

Page 9 of the document says:

2.3.  Address Type Identification

   The type of an IPv6 address is identified by the high-order bits of
   the address, as follows:

      Address type         Binary prefix        IPv6 notation   Section
      ------------         -------------        -------------   -------
      Unspecified          00...0  (128 bits)   ::/128          2.4.2
      Loopback             00...1  (128 bits)   ::1/128         2.4.3
      Multicast            11111111             ff00::/8        2.6
      Link-Local unicast   1111111010           fe80::/10       2.4.6
      Global Unicast       (everything else)


I wonder if this table should explicitly call out ULAs, and provide a
reference to the corresponding section.

(Question came up while looking at a slide I use in an IPv6 course I
teach, in which I use a modified version of this table, which calls out
ULAs).

Thanks,
Fernando
