Hi Andrew There is a limit and it based on the interface with our HSM. We are trying to figure out #'s and will have an answer for you soon.

Using the feature of pasting in a manually signed ROA, I've been able to request about 4k prefixes in a single ROA. Seeing that work, I got greedy and request 65k. That didn't work. (this was all done in the OT&E) Is there a limit to the number of prefixes that can be included in a ROA request? I can't find anything in an RFC that specifies a max number; if that's the case, is there a practical number? Here's the background of the query- Let's say you have a large summary prefix, say a /16. You've subscribed to a DDoS scrubbing service that can, on demand, originate any arbitrary /24 of your space under a different ASN. You would need to create a ROA that covers the /24s for the DDoS mitigation ASN. In this case, that's 256 prefixes, so that's manageable. How about individual /64s out of a /44, or much worse, a /32. I imagine this was exactly the concept behind the max length field that is now considered harmful. It's an interesting discussion for the operational community, but the immediate question is, what is the capacity of ARIN's hosted service? Thank you. _______________________________________________ arin-tech-discuss mailing list [email protected] https://lists.arin.net/mailman/listinfo/arin-tech-discuss _______________________________________________ arin-tech-discuss mailing list [email protected] https://lists.arin.net/mailman/listinfo/arin-tech-discuss
