There is no shortage of ASn so we have the luxury of being able to be _very_ careful.
I now realized that this is mainly about 16 bit ASn.
Even after an ASn had been reclaimed we can easily wait a significant period of time before recycling them.
And thus, this opinion changes. I don't think anything should be changed by RIPE NCC, objects need to be updated by their respective maintainers. In the best case, objects are recreated from scratch locally whenever an update occurs, rendering this moot. In the worst case, automated systems that do Weird Things (tm) will malfunction in interesting ways. Thus, I would think something along the lines of: * When ASn is being deregistered, automatically email anyone who's responsible for an object that references this ASn * Once ASn is actually deregistered, send out automated email * Once grace period is over, send out automated email * Once ASn is reassigned, send final automated email This means no effort on RIPE NCC's side, constant reminders to operators who may either need time to find out what those emails mean or under day-to-day stress (those exist, let's account for them), and overall reasonable effort to clean something up that may never be fully clean. As to what time is appropriate, I am still unsure, but "short-ish". Richard
