Hi Ronald I have added some more comments below about this specific ROUTE object you gave as an example. On 21/11/2016 01:12, Rene Wilhelm wrote: > Hi, > > On 11/20/16 10:05 PM, Ronald F.

This is one of the more extreme cases where both the prefix and ASN are outside the RIPE region. But the RIPE Database allows creation of such objects. Currently there is no authorisation done by the real resource holders and no notifications are sent to them that this object has been created in the RIPE Database. The resource holders in APNIC and LACNIC regions may not know this ROUTE object exists. Anyone can create such an object. This issue has been discussed at several recent RIPE Meetings but no consensus has been reached on how to move forward. But as you point out, there is an added complication now with some of these objects being locked. This was not part of the previous discussion on the subject. So no one is maintaining these objects, no one can delete them and maybe no one wants it to be there. And as you point out below, some people may give this (rogue) object credibility because it exists. Whoever created this object is unlikely to ask the RIPE NCC to unlock it as they may not have any valid reason for it being there. So this object is stuck in limbo... Perhaps if one of the resource holders asks the RIPE NCC to delete it they will do, but someone has to tell the resource holders it exists. cheers denis >> >> Anyway, here is my concern...
