[db-wg] Fwd: [anti-abuse-wg] 196.52.0.0/14 revoked, cleanup efforts needed

Dear Nick,

Thanks for your email.

We are planning a clean-up of these ROUTE objects. As we wanted to avoid 
deleting any legitimate objects of third parties, we checked with 
AFRINIC and they have now confirmed that these ROUTE(6) objects can be 
deleted.
We also performed a check on all of the NONAUTH database for any 
ROUTE(6) objects (using the prefix only), we found 81 routes (out of 
56,379) and 37 ROUTE6 (out of 1,568) that are not "allocated", 
"assigned", "available", "reserved" in any region. We will now inform 
the object holder and remove these objects.

We don’t think a policy is necessary for this work, but we strongly 
believe we need an approach similar to NWI-5: "Inform the object holder 
that these IRR object(s) refer to an unallocated space. We will then 
delete them after a reasonable notification." This gives people time to 
react in cases of incorrect de-registration. We will initiate a 
discussion with the other RIRs to find a joint approach on how we deal 
with similar incidents in the future.

We have also looked into publishing a list of deregistered resources and 
this will require some review internally if we plan to go down that 
route. A more straightforward approach might be for the RIRs to 
proactively highlight where we see objects in each others IRRs.

Kind regards,

Marco Schmidt
Registry Services Assistant Manager
