I don't entirely understand the process. Here's the flow chart as far as I've figured it out:
1. A sells a /20 of IPv4 space to B for, say, $5,000
2. A tells ARIN to transfer the chunk to B
3. ARIN says no, B hasn't shown that they need it
4. A and B say screw it, and B announces the space anyway
5. ???
6. ARIN receives a fraud/abuse complaint that A's space is being used by B. 7. ARIN discovers that A is no longer using the space in accordance with their RSA 8. ARIN reclaims the space and A and B are left to figure out who owes what to whom.
9. A and B ignore ARIN's email and continue to announce what they've been announcing.
10. ARIN attempts to allocate the /20 to someone else, who is not amused.
Note that at this point ARIN presumably has no more v4 space left, so a threat never to allocate more space to A or B isn't very scary. Given its limited practical leverage, ARIN is only effective insofar as its members and customers agree that playing by ARIN's rules is more beneficial than ignoring them.
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? /kc -- Ken Chase - ken@heavycomputing.ca - +1 416 897 6284 - Toronto CANADA Heavy Computing - Clued bandwidth, colocation and managed linux VPS @151 Front St. W.
