HI Tim Thanks for the review. I have added a few comments below. cheers denis On 11/11/2015 10:41, Tim Bruijnzeels wrote: > Dear working groups, > > At RIPE 70 the RIPE Database Working group asked the RIPE NCC to work > together with Afrinic on an implementation proposal to migrate > Afrinic route(6) objects to the new Afrinic IRR as part of the IRR > Homing project.

Someone made a comment about legacy space. Is this now shown in the extended delegated stats? Can we determine if it is legacy space and who is authoritative for it?

Agreed with a caveat that as a one of action the authoritative contacts should be notified that a ROUTE object exists in the RIPE Database relating to their resource. If it was maliciously or accidentally created the authoritative registrants may not be aware of it's existence. > >> (Possible) STEP 5: confirm with admin-c/tech-c equivalent as listed >> in the foreign database when a 'delete' request is received. > > If we implement this, step 3 and 4 are not needed.

From what I understood from Gert and Randy's comments it is a user's choice where to put a ROUTE object and there seem to be some reasons why they sometimes choose to put it in the RIPE Database. Is there some specific policy now that prohibits ROUTE objects in the RIPE Database for AFRINIC resources? > > It will obviously require work.
