Umm, Gordon, read what Paul said. He was saying that he suspected that the new /24s are in the swamp. And even Sprint listens to any /24s from there. 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*".

I ask because I had thought that it was just about impossible They either came from: 1) The swamp, or 2) Sprintlink customers Sean's answer to 2) would be that other providers should adopt similar filters. > to get a 24 routed at the nets defaultless core.

But if you're dual-homed to Sprintlink, Sprint'd announce it for you - and if you used a 2-year-old "Class C" obtained for "cooknet" from the NIC, Sprint would hear that and/or announce it for you (depending on whether you're a customer, of course). > that would be announced eventually in the global tables?
