Hi Denis,
Perhaps the RIPE NCC can check how many AUT-NUM objects exist in RIPE-NONAUTH for unregistered ASN´s and how many ROUTE(6) objects reference them.
Sure, that's trivial. In fact, anyone could do that with the information published by RIPE NCC and the other RIRs ;) The ripe-nonauth.db.gz on ftp.ripe.net/ripe/dbase holds 2294 aut-num objects. 100 of these ASNs are, at present, unregistered, not listed in any of the RIR's delegated stats files[1]. Except for AS266842, they had been allocated in the past. Some were de-registered in the last few months, others haven't been seen in any of the delegated stats for over a decade. 82 of the 100 unregistered are referenced in a total of 667 route(6) objects. Looking at BGP, 15 of the unregistered ASNs were seen by RIS in this morning's routing table dumps, originating a total of 395 prefixes.
In terms of a cleanup is there any argument for not doing a one time cleanup of all objects in RIPE-NONAUTH related to unregistered ASN´s?
Leaving that to the working-group to discuss. Cheers, -- Rene [1] ftp://ftp.ripe.net/pub/stats/ripencc/delegated-ripencc-latest and the equivalent for afrinic,apnic,arin and lacnic On 10/19/18 10:29 PM, denis walker via routing-wg wrote:
Hi all
Every week I get this email and usually just delete it. But as we have just been discussing cleaning up RIPE-NONAUTH I decided to look at it this week. I have some questions now.
It includes these lines: Prefixes from unregistered ASNs in the Routing Table: 45 Number of instances of unregistered ASNs: 45
This is up 1 from the previous weeks total of 44. Further down the email is a list and item 3 on this list is:
266842 UNALLOCATED 45.238.156.0/22 265680 HNTELCO S.A, HN
AS266842 is listed as unallocated. But in RIPE-NONAUTH we have these objects:
* aut-num: as266842 <https://apps.db.ripe.net/db-web-ui/#/lookup?source=ripe-nonauth&key=as266842&type=aut-num> * as-name: HNHOSTING * admin-c: HH7015-RIPE <https://apps.db.ripe.net/db-web-ui/#/lookup?source=RIPE&key=HH7015-RIPE&type=person> * tech-c: HH7015-RIPE <https://apps.db.ripe.net/db-web-ui/#/lookup?source=RIPE&key=HH7015-RIPE&type=person> * status: OTHER * export: to AS265680 announce AS266842 * import: from AS265680 accept ANY * export: to AS1299 announce AS266842 * import: from AS1299 accept ANY * mnt-by: HNHOSTING <https://apps.db.ripe.net/db-web-ui/#/lookup?source=RIPE&key=HNHOSTING&type=mntner> * created: 2018-07-06T14:32:58Z * last-modified: 2018-09-04T15:32:55Z * source: RIPE-NONAUTH

Both objects created shortly before RIPE-NONAUTH was locked down. HNHOSTING appears to be a company based in Costa Rica. They are registered in Lacnic´s DB with an allocation issued the day before these objects were created in the RIPE DB.
I don´t know why a company with legitimate address space would route it with an unallocated ASN, if in fact they created the route. But the point I want to make concerns the fact that these objects exist in RIPE-NONAUTH and have made it to the global routing table.
Perhaps the RIPE NCC can check how many AUT-NUM objects exist in RIPE-NONAUTH for unregistered ASN´s and how many ROUTE(6) objects reference them. In terms of a cleanup is there any argument for not doing a one time cleanup of all objects in RIPE-NONAUTH related to unregistered ASN´s?
