My question is as follows - We are losing customers because of this problem. It is costing us reputation and money. It is out of our control. If you were us, what would you do? We have already asked ARIN to reassign us to a "friendlier" CIDR, and they refuse.
ARIN don't guarantee routability of the blocks they allocate, and it's difficult to see how they ever could.
If you want to discuss what ARIN could or could not do, then please join the ARIN ppml list.
Perhaps this is an issue of community education, or one of needing better tools or methods for managing martian filters. Those issues are arguably both technical and operational.
The original poster doesn't have a problem with the community. He has a problem with network operators who are not part of the community and that is a reality of today's Internet that cannot be dealt with by technical tools or operational methods. But there are non-technical and non-operational actions actions that ARIN could take to help. The details of those actions and whether or not ARIN members want to act are matters for the ppml list. --Michael Dillon
