Hi,
Is there any list (exhaustive or not) of feeds/sites/places/things the
NCC should depend on in order to reassign numbers?
Does the NCC have authority over them to force the cleanup?

Hello DB WG,
As RIPE has been handing out new ASNs from previous allocations that have been
returned for several months now, I wanted to ask if there’s any plan to clean
up an entry somehow before reassigning the AS.
With the current system you can request an AS, get it, and then have ROAs
(ASPAs too?) / route{6,} / as-set objects, etc. from the previous one or more
owners.
I recently got an AS with valid ROAs and route objects for some IPv4 still
pointed its way from a couple of operators ago (according to the bgp.tools
history).
For bonus points, it’s also included in a DE-CIX IXF feed and shows up as
connected there :)
Does it make sense to clean up objects or notify entities including an AS upon
its return back to the available pool? Since you can’t really know who will get
it and when, it’s unlikely you really mean to authorize announcements with a
ROA, or IRR routes. It also probably doesn’t make any logical sense to include
it in an as-set.
I stumbled upon this when I tried generating filters with bgpq* and it added a
few unknown /22s without me recognizing them. Pim here (in Cc) also had the
same question :)
Thanks,
Antonis
