How would you propose to handle the case where an organisation has their own IP space which isn't currently advertised and then you receive a request from a third party to route it to them?
First I would suggest they register their claim to use the IP address with the appropriate registration agencies. As I understand it, every register has a method for recording further delegations. It is providers who choose to create the problem by not recording the delegation.
If for some reason they can't change the organization of record for the IP address, there is a concept called a "Letter of Agency" which is used when someone wants to authorize a third-party to take actions on their behalf. If the third-party does not have a LOA from the coordinator of record for the IP address, I wouldn't view it as a valid request.
I'm not sure you're being clear. If someone has portable /24 or /16, and does NOT do their own BGP, but contracts with ONE ISP to do that advertisement. How do other ISPs know that ISP has permission? We could point to the RADB, but it's chock full of bogus data. We could point to ARIN, but their database just says the owner of the net in question is whomever it is. Those who own that space have a legitimate right to use that space, so telling them to get ISP-provided space is a non-starter. I agree it's a problem in need of a proper solution. The solution has to account for portable address space not owned by providers. -- ----------------------------------------------------------------- Daniel Senie dts@senie.com Amaranth Networks Inc. http://www.amaranth.com
