Right, and Im answering my own question here, for (8) about the reclaiming -
what upstream is going to stop carrying prefixes from a downstream that's
'illegally' announcing them? Is this upstream going to cut that customer off and
lose the revenue, just to satisfy ARIN's bleating? From what I gather, all that
ARIN can do is remove the NS records for the i-a.a reverse zone for the offending
block, making SMTP a little trickier from the block, but not much else.
Unless I didnt see the other large sticks ARIN's carrying? I've never seen them
send hired goons to anyone's door... yet?
