] The swamp is basically the old "Classful" address space.
] What Sean did was to say "You can use your old 'Class C's
] but I have to stop the table-size growth in *new allocations*".

] =========
] Then apparently I have misunderstood what the swamp was/is.  I thought it
] was just an unaggregated area and didn't understand why.  Is there text
] somewhere that explains very clearly the swamp and the policies attached
] there to?

  I see a question that says why was it not aggregated?

  It wasn't aggregate because at the time of dispersion, there was
  no need to allocate, routing table growth was not a significant
  factor in internet address allocation.

] Is the swamp then bounded by class c addresses warranted as routable when
] they were handed out?  Are you saying then that the defaultless core
] routability of class c's from the swamp is, as of now, guaranteed?

  Perhaps I'm a bit of a wild card, but I don't see any IP address
  as routable based on official policy or origin of assignment.  IP
  Address space is routable because each [I|N]SP that might have
  occasion to route the space, agrees to.  They agree to because it
  makes economic sense, or, in some cases *cough sprint* it does not
  make economic sense to route 207.99.99.0/24 (apologies to NAC.NET,
  I just made the net up, and I know they have a /18, so the example
  is invalid...) .  I firmly believe that explainable economic decisions
  are in the best interest of the net, and if they're not, the
  company making poor economic decisions will leave through natural
  [economic] selection.

] 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
] FOR WHICH THE OWNERS COULD DEMAND ROUTING?

  Lots.

] In other words are these 5,000 new class c's just the beginning? Or are
] they, hopefully the end?

  Neither, they're a holdover from a more carefree time...

  At least, that's my 3 minute rant before my next meeting... :)
