ASN reference cleanup
by Rob Evans 17 May '14

17 May '14

Folks, For any RPSL lovers among you that weren't at the Address Policy WG meeting this morning, the topic of cleaning up referenced AS numbers came up again. There are about ~2,000 16 bits ASNs that have been returned, but are still referenced in the import/export lines of other aut-num objects, either directly or via as-sets. There will be more discussion of this in the Database WG this afternoon, but I thought I'd mention it here as it has implications for those on this list that use RPSL. Cheers, Rob
