Reassigning Referenced AS Numbers

These AS Numbers are referenced in a number of objects - mostly other AS Number objects in the policy statements of the "import:" and "export:" attributes and various set objects. Also there are route objects referencing them while such announcements do not exist in BGP. 

Based on the feedback from the RIPE community, we are issuing referenced ASNs (that are not globally routed).

The RIPE NCC sends emails to the maintainer and contacts for the RIPE Database objects that reference returned AS Numbers, asking for these references to be removed.

More information on how the RIPE NCC reuses returned Internet number resources.
