Hi Paul,
you comment leaves me confused. 25,000 24s up 20% in the last six months
means 5,000 NEW prefix 24s in the global routing tables. Where did they
come from? I ask because I had thought that it was just about impossible
to get a 24 routed at the nets defaultless core. And that this
impossibility has been around for at least the last 6 months.
I thought that if "cooknet" as a new MCI customer has a 24 handed to it by
mci all nice and cidrized that "cooknet's" 24 would never appear in your
list being aggregated by mci along with other 24s to make a smaller prefix
that would be announced eventually in the global tables? Have I
misunderstood something or is theory diverging from practice.
