There are about 80 networks out of the 12/8 netblock allocated 
and advertised.  Most of these are /19's, some are larger and 
a few are smaller (a couple of /20's).  As someone from AT&T said 
earlier in this thread "they are being allocated to customers as 
if it were a nonportable block and the only way you will see the 
more specific routes is if the customers multihome"  (or something to 
that effect).  I haven't seen any of these subnetworks of 12/8 advertised 
by anyone other than AT&T.
