yes, it matchs whatever that starts with binary 001.

None, AFAIK.

from pTLA formats document:

The original TLA and NLA ID-s as specified in [AGGR] are as follows:
         | 3 |  13 |          32         |   16   |    64 bits      |
         +---+-----+---------------------+--------+-----------------+
         |001| TLA |       NLA ID        | SLA ID | Interface ID    |
         +---+-----+---------------------+--------+-----------------+

...
Additionally:

Therefore, the first 12-bits of the NLA ID space are assigned as the pTLA 
that defines the top level of aggegation (backbone) for the 6bone. This 
would eventually provide for 4096 6bone backbone networks, or pTLA-s, and 
leaves a 20-bit pNLA ID for each pTLA to assign as needed.
         |     16    |   12  |   20      |   16   |    64 bits      |
         +-+---------+-------+-----------+--------+-----------------+
         |  0x3FFE   | pTLA  |   pNLA    | SLA ID | Interface ID    |
         +-+---------+-------+-----------+--------+-----------------+


Sample IPv6 address:

        3FFE:8000:0001/48
 6bone _|||| |||| ||||___site
             |||| |
 b/b site____|||| |
                | |
 transit________|_|
