My preference would be to start such a global registry. I would love it if at least RIPE, APNIC and AFRINIC (who all use very similar data models IIRC) could combine databases. Having separate (but in reality partially overlapping) databases for a global resource will always result in discussions like we have had over the last two+ years IMHO. Let's make an effort to form a single point of reference. Cheers, Sander

It can't be done because several other RIRs don't provide the authentication hooks to be able to do this. On the question of this work item, what I would like is a mechanism to distinguish between route objects which have been verified using the trust grandfathering mechanism deployed by the RIPE NCC, and those which have not. There are many ways of doing this, e.g. 1. Option B: remove all non RIPE objects from the db. 2. use different source: tags to distinguish between ripe space and non ripe space. 3. leave whois.ripe.net as it is, and create a different database consisting of only authenticated route: objects. 4. leave whois.ripe.net as it is and create a different database view which, if queried, will return only objects which have been authenticated. Options for handling this might include: 4.1. same db on different hostname providing a different view 4.2. a new ripe-181++ tag identifying authenticated objects My preferences in order are: 2, then 4.2, then 4.1, then 3, then 1. No doubt there are plenty of other ways to crack this particular nut. Denis's description of Option C perpetuates what is a operational problem which has serious and ongoing consequences in the area of prefix hijacking. It would not be realistic to characterise the current situation as "if it ain't broke...", because it is identifiably broken, and it is this breakage which has led to this discussion. If we could solve this problem in a way which was operationally portable to other RIRs, that would be a bonus. Nick

I wonder if this is the right question to ask, or we should step back and ask the question what can we do to provide a secure routing registry where people can document "this prefix will be announced by that AS" in a way that is a) strongly authenticated (= only the current holder of the address space can create such a route: object), and b) easy to use for people building filters (= not having to walk 5 different IRRDBs to find the set of prefixes announced by a possible customer)? instead? A, B or C may be a consequence of this. In any case, given that we have no proper global registry, and we have lots of cross-region routes ("addresses from RIR A, AS number from RIR B"), we need to find a way to document these properly. From a user perspective, I like to have all route: objects for my customers in a single place (RIPE BD, that is), so for me, "A" would be most convenient - but we need to add some sort of cross-RIR authentication layer.

Either A or C, insofar as they are different. Not allowing "foreign" resources in the ripedb denies the reality that there will always be RIPE-allocated prefixes originated from non-RIPE-assigned ASNs and vice versa. One could make an argument for not allowing route: objects where both the prefix and ASN are from outside RIPE. This would complicate (or make impossible) any attempt at automating acceptance filters, unless and until this information is available from other (trusted?) sources. As it currently stands, this would, on balance, be worse for the "good of the internet". cheers, Sascha Luck
