AT&T has been allocating customers from 12/8.
And how many routes has it been split up into?
According to nitrous, they are not announcing anything more specific than
12/8.

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.

Those leaked more-specifics are only seen by customers, due to some
old vendor policy constraints. We'll fix that pronto.

One /24 from 12/8 is currently visible thru certain Internet vantage
points:
12.10.231/255.255.255
