As for the two /8s -- not quite.  Back in the 1980s, AT&T got 12/8.  We soon learned that we couldn't make good use 
of it, since multiple levels of subnetting didn't exist.  We offered it back to Postel in exchange for 135/8 -- i.e., 
the equivalent in class B space -- but Postel said to keep 12/8 since no one else could use it, either.  This was all 
long before addresses were tight.  When AT&T decided to go into the ISP business, circa 1995, 12/8 was still lying 
around, unused except for a security experiment I was running.*    However, a good chunk of 135/8 went to Lucent (now 
Alcatel-Lucent) in 1996, though I don't know how much.

Note that this isn't my regular email account - It's still experimental so far.
And Google probably logs and indexes everything you send it.
