Not true - you can easily run a whois query on whois.radb.net specifying multiple sources, including RIPE: % bgpq3 -S RIPE,APNIC,LACNIC AS-FOO In fact, there is no way of writing a functioning irrdb querier which can't handle specifying arbitrary irrdb source: options on a per-ASN basis.

Is an option D: create a central IRRDB with authentication hooks into all RIRs completely out of the question? It certainly sounds like the technologically most elegant answer. Modulo legacy resources, no unauthenticated irrdb objects should then have to exist. The trust root could be shared between the RIRs as is seemingly done with RPKI these days... cheers, Sascha Luck

It seems it would be low hanging fruit to use the "source:" tag to distinguish between objects that are authenticated and non-authenticated by using "source: RIPE" and "source: RIPE-NONAUTH". The above described small step bridges the needs to many who expressed opposing views in this thread: some want to be able to register anything in the RIPE DB and some want it to be pristine and purge all non-RIPE-managed space from the IRR DB. By decorating the two types of data with the appropriate "source:" attribute I think we are meeting in the middle. By using a different "source:" attribute for RIPE vs non-RIPE space it becomes easier for operators to cherry pick which data they want to use in the creation of their routing security filters. Should the group decide to proceed with option A or C (between which I don't see a difference), at the very least it should be visible to my tooling which objects represent what type of data.

But if RIPE allows the creation of objects for which it has no authority over, what are users supposed to do when they see the contradicting data coming from RIPE and AFRINIC (to follow your example)? That's also the reason for the existence of the --resource query flag. Question is, why would we keep data that is not authoritative (and not mirror) in the RIPE DB?

You are right, RPKI does fit the bill in a number of ways, and I look forward to the operators taking advantage of the good bits. However this does not preclude the RIPE community from improving the quality of another commonly used source: IRR. As you know there are only 2 or 3 networks on this planet using RPKI in their operations, while I can point at many more networks using IRR to build their whitelists for provisioning. As you know there is a feature gap between IRR and RPKI. RPKI doesn't have an "AS-SET"-like replacement, and not all the RPKI TALs are as easy to obtain as their equivalent IRR data. > a least it's a more credible argument than thinking encouraging ipv4 > run-out will increase ipv6, as opposed to nat, uptake. < dripping > sarcasm > OK, this seems off topic.

You as network operator can easily poll the APNIC or AFRINIC database. There are even a number of "IRR aggregation services" such as NTTCOM and RADB which mirror a ton of IRRs for your querying convenience. The "convenience" argument seems a slippery slope: as your customer base grows, you'll be encouraging more and more non-RIPE space to end up in the RIPE database (even though it could be in an authenticated source such as APNIC). Why? To what benefit? Why would you be supportive of the continuation of type of pollution? Isn't a simpler solution to drop the "origin:" attribute verification and only authenticate against the "inetnum:" authentication hierarchy? This way an ARIN-managed ASN can easily register RIPE-managed space in the RIPE database and it would be strongly authentication against the "inetnum:" I think that RIPE managed space belongs in the RIPE database, however non-RIPE-managed space (APNIC, AFRINIC, ARIN, LACNIC, chunks of legacy) have no place here since we cannot authenticate them.

RIPE Access Account: Cannot change registered e-mail address back to previously one
by Christoffer Hansen 10 Oct '17

10 Oct '17

RIPE Database Working Group <db-wg(a)ripe.net> Am I the only one who have previously wondered about the following issue... (?) 1. Register a RIPE Access Account with [account_1(a)example.com] 2. is changed to [account_2(a)example.com] 3. later tries to change registered RIPE Access Account e-mail back to [ account_1(a)example.com]. I'am not allowed to do this. RIPE NCC's website simply does *not* allow me to do this. Refer to the following pictures for clarification. *Changing the e-mail address back to [account_1(a)example.com <account_1(a)example.com>]* *× * *Creating a new RIPE Access Account for [account_1(a)example.com <account_1(a)example.com>]* *× Trying the forgotten password function for [account_1(a)example.com <account_1(a)example.com>]* *× * Regards, Christoffer Hansen. gpg: c8b3 82a8 a1cd cdb7 71fe b24c c654 948f da86 becd
