Dear DB-WG,
Speaking in individual capacity.
In RFC 2622 section 5 specifies the naming convention for AS-SET objects. https://www.rfc-editor.org/rfc/rfc2622#section-5.1 There basically are two styles:
* "short" (example: AS-SNIJDERS) * "hierarchical" (example: AS15562:AS-SNIJDERS)
Problem statement ================= (...) Solution proposal ================= I think the solution is to - GOING FORWARD - disallow creation of new AS-SET objects which follow the 'short' naming style.
I support that. I have been confronted to issue with one of my downstream, which used to (legitimately) have AS-KIWI as AS-SET at RIPE IRR. However, AS-KIWI also exists in AFRINIC, which was parsed first by one of my connectivity provider, leading to incorrect filters (and, worse, anti-spoof access-lists). I solved the solution by making my downstream use another as-set, but I think it could be easier to have hierarchical IRR naming convention only. But it should become a mandatory thing on all IRR.
