Ah, but what happens when the NIC starts allocating out of 208/8?

And so how many of your customers have unreachability problems for how long
before you realize that the NIC is allocating out of 208/8?

<Insert levity, I'm not trying to start flamage.>

And is the NIC going to allocate around the 208/8 terrorists?

Avi

Most likely the same thing that happens when the NIC allocates out of
any other part of the address space.. Folks will register these prefixes
in the IRR of their choice, and they won't be filtered any more. :) Any
problems in that area are handled graciously by most providers, and ANS
is happy to assist. :)

Well, it looks like a fat finger to me...I see that 207.0 - 207.3 is assigned
to MCI. I'll be the client was allocated these out of 207 instead of 208,
and just mistyped them.

for my part, when 208/8 starts to be valid i will stop filtering it.

That was ans that responded. The filtering he's refering to is the RADB,
obviously, which is an easy filter to fix, if you know what you're supposed
to do with it. ;-)

Hm, interesting, Rob. So what happens when we register
something the NIC hasn't allocated yet in the IRR?

Sean.

Most likely something similiar to what is happening now to every
provider that doesn't filter. It just provides an extra hoop to jump
through. As I'm sure you know, most of these problems are not the result
of maliciousness, but unfortunate error. The IRR's are some
protection. They are not a perfect answer.

Your baiting again Sean. The same thing that happens when
ChinaNet starts advertising the CIDR block 204.94.0.0 - 204.97.255.0
or EUnet starts advertizing block 18/8.
