It's not necessarily unaggregated...
I'm not sure, it's possible that Sean might have described the swamp as
basically space above the a/b space and < 205/8.
At the Los Angeles IETF I tried to define the terms "Swamp" and "Toxic
Waste Dump" as follows:
* The Swamp is the 192.0.0.0/8 addres space that is routed.
* Each and every /24 in the Swamp is part of the Toxic Waste Dump (twd).
> Of the class cs from the swamp how many are now being routed at the
> defaultless core? HOW MANY ADDITIONAL CLASS Cs FROM THE SWAMP ARE THERE
No clue, but we could find out.
You might not like/agree/understand the above definitions, but... given
the above definitions the current sizes are:
Size(swamp) = 6549
Size(twd) = 5555
